The Committee acts as a forum for the exchange of
information on a number of initiatives aimed at
recruitment of engineers and technologists for the mining
industry.
The Phoenix programme, which is co-ordinated by the
Chamber of Mines of South Africa (COM), has focused
on the provision of resource packages for high schools.
Details on the extraction of South African minerals are
provided as optional science subjects for Std 8. Packages
for copper and manganese are already in use in many
schools, while gold and coal packages are under
development Experiments are included, and the CaM is
providing training.
The University of Pretoria and the University of the
Witwatersrand are collaborating with the teachers'
training colleges in their respective cities on special
courses for gifted children, aimed at introducing them to
various aspects of the minerals industry. These
arrangements include lectures and visits to mines and
research facilities. Both programmes have been well
supported
The University of the Witwatersrand is also offering
vacation work to schoolleavers; this is an integral part of
the research effort in the Department of Metallurgy and
Materials Science. Project Seed, as it is called, requires
the students to analyse information and to produce a small
report.
The SAIMM supported the initiative of the Society of
Professional Engineers (SPE) and the South African
Engineering Association (SA VI) on the development of
technological man-power. Support has been obtained from
industry and the Foundation for Research Development at
the highest level for the co-ordination of financial support
for universities and technikons.
The SAIMM made modest financial contributions to
the above-mentioned activities.

In addition to the International
Deep Mining
Conference (IDMC) , three events were held during the
year.
In July 1990, a school entitled 'Ventilation and Refrigeration'
was held over three days. Registered
delegates numbered 65, but attendance was somewhat
lower. While excellent subject matter was presented at the
school, it is clear that, in the present economic climate,
schools should be of shorter duration.
In May 1991, a one-day colloquium, entitled'Communications
and Monitoring
to Improve Mine
Productivity and Safety', was held. This proved to be
popular and attracted a full house of 103 delegates.
Eleven interesting papers were squeezed into the day.
In June 1991, a school entitled 'Mine Valuation and
Grade Control' was held over two days. The budget was
again exceeded, 134 delegates attending.
Current planning is for a series of five one-day
colloquia to address productivity and survival in the goldmining industry. Work has also started on two
international conferences-the concurrent Mass Mining
and Coal Mining Conferences to be held at the Electra
Mining Exhibition
in September 1992, and the
International Backfill Conference to be held in 1993.

A two-day conference on 'Innovations in Metallurgical
Plant' was organized as a parallel session with 'Deep
Level Mining and Materials Engineering'
at the
International Deep Mining Conference held at NASREC
from 17th to 21st September, 1990. The conference was
held in conjunction with the Electra Mining Exhibition. A
total of 97 delegates attended the Extractive Metallurgy
sessions, and 20 papers were presented on a wide variety
of topics. Presenters included two overseas authors.
A three-day school on 'Practical Design of Com306
SEPTEMBER 1991
minution Processes' was held at Megawatt Park from 14th
to 16th May, 1991. The objective of the school was to
provide a wider insight into modem theory and practices
employed in the comminution routes, particularly for
those whose experience had previously been confined
mostly to Witwatersrand gold ores.
Mr Derek Barratt of Wright Engineers in Canada was
principal lecturer, and his lectures were complemented by
contributions from local experts to provide a South
African perspective. This successful school was attended
by 103 delegates, including the lecturers.
A one-day colloquium on 'Bacterial Oxidation' was
held on 18th June, 1991. Papers presented included 'Biooxidation of arsenopyrite and pyritic gold ores', 'Bacterial
leaching of copper', and 'A review of the commissioning
of several bio-oxidation plants'. A total of 84 delegates
attended.
A school on 'In-Pulp Technology' and a colloquium
on 'Industrial Minerals' are scheduled for the latter half of
1991. The Special Interest Group on Process Control,
which was formed during the previous year, had an active
programme, with visits arranged to JCI's Cooke Plant, the
Rustenburg Precious Metal Refinery, and Mintek.

The first South African colloquium on 'The Engineering
Development of Composite Materials' took place at the
Indaba Hotel on 23rd July, 1990. The Colloquium was
held in recognition of the major potential for application of
composite materials in South African industry, and provided a forum where interested parties from industry could
meet suppliers of composite materials. The fundamentals
of the production and performance of such materials also
received a great deal of attention. The scientific approach
was introduced and well covered by the invited lecturer,
Professor Adams from the University of Bristol, UK.
The Committee participated in the International Deep
Level Mining Conference and held a technical session on
18th and 19th September, 1990 at NASREC. This
technical session, 'Application of Materials Engineering
in the Mining Industry' underlined the importance of the
work carried out by materials engineers, and contributed
to the forging of closer bonds between this discipline and
the mining industry.
The Committee also assisted the Publications Committee in preparing the Proceedings
of the First
International Corex Conference for publication.

In September 1990 the International Deep Mining
Conference was held over four days at the Electra Mining
Exhibition. Despite a severe downturn in the gold price at
that time, a total of 539 delegates attended; these included
64 overseas delegates from a wide spread of countries.
The SAIMM was assisted in this venture by the
Association of Mine Managers of South Africa, the
Association of Mine Resident Engineers, and the South
African Institution of Mechanical Engineers. The input of
these organizations, particularly with regard to the
technical content of the Conference, was invaluable, and
sincere thanks are due to all who were involved.
Twenty papers were presented in the category
'Innovations in Metallurgical Plant', 22 papers under
'Applications in Materials Engineering in the Mining
Industry', and 87 papers under 'Technical Challenges in
Deep Level Mining'. The high standard of technical
content, presentation, and publication of the papers, as
well as the comprehensive technical coverage of the
Electra Mining Exhibition, made this a most successful
event.
The event was opened by the President of the Chamber
of Mines of South Africa, Mc C.G. Knobbs. The Minister
of Mineral and Energy Affairs and Public Enterprises, Dr
Dawie de Villiers, spoke at the banquet. Social events
were well attended and enjoyed by the delegates.
The Conference volumes constitute an important
mining and metallurgical reference work, and sales of
these volumes have continued to be steady since the
Conference.

of awareness and responsibility of its members towards
the environment.
The strategic objective will be pursued through education and training; in the Journal of The South Afican
Institute of Mining and Metallurgy; by awards (by the
support of EPPIC awards and the initiation of SAIMM
awards); by integration with other forums, organizations,
or groups concerned with conservation; by the promotion
of public relations; by the creation within the SAIMM,
particularly at Branch level, of special-interest groups on
the environment; by liaison on environmental regulations
and protection with other associations, tertiary educational
institutions, and government departments; and by being
in a position to take a stand on environmental issues.
Five members of the Committee visited Richards Bay
and held discussions with Richards Bay Minerals (RBM),
the Zululand Environmental Alliances (ZEAL), the St
Lucia Action Group (SLAG), and the Natal Parks Board
to gather opinions on the possible mining of titanium
sands in the St Lucia area. One could not but be impressed
by the rehabilitation work carried out by RBM on the
current lease area, for which the company received
EPPIC's National Premium Award for integrated
environmental management in 1989. The question of
whether mining should be allowed to extend into the St
Lucia area is a complex one, and the Government's
decision must await the thorough assessment of the
environmental impact of this activity required by the
Minister of Environment Affairs.
After considering the merits of several worthy candidates, the Committee put forward New Vaal Colliery as
the Institute's nomination for EPPIC's National Premium
Award in 1991. Members can be proud that this award
was made to New Vaal Colliery at the World
Environment Day Symposium on 5th June, adding to the
successes of RBM mentioned above, and the De Rust
open-cast silica-mining operation of Consol Industries,
which won EPPIC's Johannesburg Regional Award last
year-also on the recommendation of this Committee.

Dr G.A Fourie, Chairman
Mining
The Organizing Committee, with the assistance of
Professor AN. Brown, arranged a number of visits to major
open-cast and strip-mining operations in South Africa. Sites
visited include Optimum and Duvha, both of which use
large walking draglines for overburden stripping.

Delegates were briefed on the latest technological
developments in surface mining techniques, with special
reference to the rehabilitation
of mined-out areas.
Conservation of the environment is becoming a major
factor to be considered when surface mines are being
planned and operated.
The Group is seeking closer co-operation with the
South African Institute of Quarrying and other
organizations in an effort to improve its service to the
mining industry.
It is therefore actively involved in establishing
academic courses at designated technikons and technical
colleges to facilitate specialist training in surface mining.
2.8 Special Interest Group-Process
Control
Dr M.H. Moys, Chairman (co-opted)
This group has continued with its visits to plants and
research institutions where process-control developments
are of interest
The procedure followed during a visit is generally as
follows. After a start and introduction at about 14:00,
several short presentations are made by plant personnel on
topics of relevance to process-control developments on
the plant to be visited. Delegates are then taken through
the plant in small groups. The afternoon closes with a
social event.
The visit to the Precious Metals Refiners (pty) Ltd in
Rustenburg at the end of 1990 was poorly attended but
greatly valued by the participants. One result of the poor
attendance was a decision that, in future, announcements
of the visits of this Interest Group would be sent to all
SAIMM members.
Another visit was to Mintek's Measurement and
Control Division. This was an exceptionally wellorganized visit Three groups were taken on a tour of the
Division's major projects, viz multi variable control,
measurement of the size distribution of ore on conveyor
belts, the use of cyclune flare angle in the control of
grinding mills, etc.
Two more visits are planned in 1991: one to Western
Deep Levels in July, the other to AECI Process
Computing in October.
Visits are generally highly valued, and we encourage
SAIMM members to take advantage of them.
2.9 Special Interest Group-Computer

P. van Schaardenburgh, Chairman
The past year has seen a very low level of seminar
activity. Although this may seem to be disappointing, the
Committee of the SIGCA identified the need for
repositioning and restructuring in order to do justice to the
catalytic process of bridging the gap between the dataprocessing profession and the customer base to which this
profession delivers a service.
The Committee decided therefore to concentrate on the

following:
restructuring of the Committee, so that full members can be recruited only from the mining houses
and mining companies, and representatives from
learned societies and vendor companies may be seconded by invitation;
the adoption of a long-term approach in terms of
seminars, colloquia, conferences, and schools, and
the subsequent preparation of a programme;
the inclusion of input from universities and technikons in the execution of the above programme.
.
.
The Committee is negotiating a two-year programme,
the fruits of which will become apparent during the course
of 1991.

Mr Paul White allocated specific responsibilities to
members of his Journal Committee. This focused attention bore fruit in increased advertising revenue and a
greater variety of papers, the latter being in line with
efforts to increase interest in the Journal from all members of the Institute.
The costs of publication increased dramatically. With
the withdrawal of Mrs Claire Keamey from typesetting,
they will be even higher in future.
This led to an evaluation of desk-top publishing (DTP),
which indicated that, in the light of escalating publishing
costs, the Institute will derive economic benefits from the
use of such equipment.
If an increased number of books, monographs, or proceedings are published, DTP will contribute significantly
to the funds of the Institute. It is believed that such material is available within the minerals industry. Other benefits of DTP will be: improved quality of diagrams and the

ease with which the layout of the Journal can be changed
and controlled. This will be of advantage in the current
drive to make the Journal more readable.
Council approved the purchase of the necessary equipment at its May meeting. The secretaries for the Journal
and book publications
will, in future, form the
Publications Team. Mr Rick Mohring led his Book
Publications Committee enthusiastically but struggled for
some time to get volumes in the pipeline into print. The
problem of authors not meeting deadlines continues to
delay publication. Editing to maintain the high technical
standards expected of the Monograph Series has also
delayed publication.
Consideration will be given to rapid publishing in the
Sundry Publication Series in future, while the subject
under consideration is most topical.
The high cost associated with publication of the IDMC
volume on time lent support to the decision to install DTP.
The change in the fortunes of the minerals industry has
resulted in a reduction in job advertising. The Institute's
News on the Job Market has suffered in line with this.

JOURNAL
OF THE SOUTH
AFRICAN
INSTITUTE
The 1989190 goal of increasing the readability of the
Journal through the introduction of more non-research
material has been, and will continue to be, implemented.
Thus, the past year has seen articles on innovations in
technology and management, new developments in the
industry, and legal aspects that have an impact on the
viability of the industry. Mineral and operational reviews
have also been featured. These articles, together with
high-calibre research articles that remain the backbone of
the Journal, have significantly increased its readability for
the general membership.
The financial aspects of the Journal continue to
command attention. Operational deficits continue to
increase as a result of lower overall revenues and
escalating production and overhead costs. Earned revenues
from advertising for the year have shown an overall net
increase of some 35 per cent despite a small deficit from
job advertising, which has been virtually discontinued. The
issue of accounting revenues from exchange rates,
exhibitions, grants, and a contribution from membership
fees needs to be addressed if Journal revenues Me to be
meaningful. On the cost side, production costs have in
some instances more than doubled. The new desk-top
publishing system that has been purchased should more
than contain these spiralling costs.

Two volumes were completed during the year. The

Level Mining Conference (IDMC), was published before
the Conference was held in September, and a book on the
Corex process has been completed. The latter publication
was published
with the support of Iscor and
Voest-Alpine.
Five volumes are in the production stage, and a further
two potential volumes are under consideration. Production
schedules have once again had to be extended because
deadlines have not been met by authors.
The volume of sales of Institute publications was
satisfactory for the year, and the Committee's marketing
drive continues. The storage problems experienced last
year after the move from Kelvin House have been
satisfactorily resolved. The reorganization of book stocks
has enabled the redundant stock position to be reviewed.
Redundant stock will be made available to technikons and
universities.
Caroline Jansen returned as Book Publications
Secretary during the year, and her valuab1e contribution is
appreciated.

As can be seen from the following reports, the
Branches of the Institute had another active year. Branch
Chairmen and their committees must be congratulated on
their efforts to arrange stimulating meetings and outings
for their branches.
The Johannesburg
and Pretoria Branches have
followed the lead of the Western Cape and Vaal Triangle
Branches by holding functions aimed at students.
A new branch was started in the north-western
Transvaal under the enthusiastic leadership of Dr Larry
Cramer. The inaugural meeting, which was attended by
the Chairman of the Regional Development Committee
and the President Elect, was well supported, and bodes
well for future activities in the interest of SAIMM members in the region.
Discussions were held with the Association of Mine
Managers of South Africa on possible areas of closer cooperation. Good progress was made during the year.
Interaction with other bodies active in the mining and
metallurgical industries continues.

again had a very busy and successful year. As mentioned
in the previous Annual Report, the Institute vacated its
offices in Kelvin House and moved to new premises in
Cape Towers. The loss of facilities presented difficulties
for the Branch with respect to venues for general
meetings. The Branch is now required to hire a venue at
commercial rates, and has to rely on sponsors for its
events. In this regard, the Committee, on behalf of all its
members, wishes to express its gratitude to all those
companies and organizations that have sponsored the
Branch's general meetings held in the evenings, and
helped to make them a success.
The concept of general meetings that are held in the
evenings every two or three months and at which multidisciplinary presentations are given on projects or topics
of general interest has once again proved successful. This
success has been manifested by attendances of up to 250
people on the various occasions.
The following general meetings were held:
July 1990(AGM):VenetiaDiamoodProject (McB. Ainsley)
November 1990:RichardsBay Minerals (McRD. Macpherson)
February 1991:Sasol/SecundaCollieries(McC,J. Cloete)
May 1991:South Deep Project (McW.A. Nairn).
The Committee thanks tke organizations involved for
sponsoring the cocktail parties after each of the meetings.
These events provide an important opportunity for
members and their guests to interact on a social level.
Fifty-year Membership Awards were presented to the
following members during the year: V.C. Barnes, A.H.H.
Davison, E.T. Dunstan (posthumously), A.RC. Fowler,
E. Margo, E.R Rudolph, and I.S. van Eyssen.
A students' evening was held on 11th September, 1990
at which four students (two from the University of the
Witwatersrand and two from the Witwatersrand Technikon) gave presentations on their final-year projects.
Attendance was by invitation, and the presentations were
followed by a cocktail party sponsored by the
Johannesburg Branch. Approximately
100 people
attended, and the evening was most successful. It is
intended that this should be an annual event to further
strengthen the links between tertiary education
institutions, the SAIMM, and industry.
Approximately 100 people attended an afternoon visit
to the Johannesburg Stock Exchange in July 1990. A presentation on the general workings of the JSE, with an
explanation of the Option and Futures Market, was
arranged by Fergusson Brothers, which also sponsored a
cocktail party.
A two-day visit to Keeley Granite, Buffalo Fluorspar,
and Rooiberg, which had been arranged for August 1990,
was cancelled owing to lack of support. Because of the
low levels of interest displayed in the past, the Committee
does not intend to arrange further two-day visits in the
fore- seeable future.
An excursion to Valindaba, kindly arranged by the
Atomic Energy Corporation, took place on 21st March,
1991. The 34 people who attended were provided with an

opportunity to view a wide and interesting variety of
technologies.
Another technical visit was arranged to the Rand
Refinery. This always proves popular, and is well supported. The visit took place on 6th June, 1991, and was
fully subscribed.
The Branch wishes to reiterate its thanks to all those
individuals and organizations who gave of their time and
provided sponsorship to make the Branch functions the
success they were. Also, thanks are due to the SAIMM
Secretariat for the service and support it provided, and the
interest it shows in the activities of the Branch.
Mr Frik Blaauw, the General Manager, introduced the
group to the guides and gave a talk on the history and
operations of the mine. A tour of both surface and
underground activities took place on the Friday. A pub
night was organized in the evening at which members
enjoyed the company of the local community. Saturday
was spent playing golf by the more energetic members.
Two general meetings were held during the year. The
first was held in the;Free State Geduld Mine canteen on
23rd October, 1990, where Mr Bill Odendaal, the Mayor
of Welkom, gave a presentation on 'Changes to Local
Government in the New South Africa-Proposals for the
OFS Goldfields'. He explained the implications of the

function, and hopes to attract them to similar events in the
future.
The Branch, together with the Department of Materials
Science and Metallurgical Engineering of the Unive~sity
of Pretoria, also initiated a Metallurgical Forum during
the year. The aim of this forum is to stimulate interest in
metallurgy and also to bring students into contact with
senior members of the profession. The Committee was
indeed fortunate to fmd excellent speakers for the initial
meetings and hopes to continue in this vein.
Mc Jack Hewitt, Group Manager: Research and Development of Middelburg Steel and Alloys, addressed the
meeting on 20th February, 1990 on 'Innovations in the
Annealing of Stainless Steels'. Dr Brian Loveday, Consulting Metallurgist of Anglo American Corporation,
addressed a meeting on 20th March, 1990 on 'Design and
Control of Milling Circuits'. Mc Peter Bailey, Consulting
Metallurgist of Gengold, gave a talk on 'The Operation of
Run of Mine Mills' on 17th April, 1990. Mr Noel
Peverett, Assistant Consulting Metallurgist of Gold
Fields, gave a talk on 'Recent Developments in Thickener
Technology' on 15th May, 1990. Three more forums are
planned for the rest of the year.
The Committee is satisfied with attendance at the
events hosted by the Branch, but would like to attract
more of the senior members on a more regular basis. We
are encouraged by the involvement of students from the
Departments of Mining Engineering and of Materials
Science and Metallurgical Engineering of the University
in the activities of the Branch, and see this as a means to
introduce them to the profession and the Institute.

The Annual General Meeting of the Branch took place
on Tuesday, 19th June, 1990 at the US KO Club in
Vereeniging. The meeting featured the immediate pastPresident, Dr Oskar Steffen, who outlined his past year as
President of SAIMM. The guest speaker was Dr Phillip
Lloyd of !PC who spoke in his usual entertaining manner
about pollution, and gave his own particular interpretation
of a long-standing South African problem.
The Dr Arnold Mol function took place on Tuesday,
14th August, 1990 at the Iscor Recreation Club. The
meeting was originated by our Branch of the SAIMM
(through Mc Kenny Beard), but was co-hosted and coorganized by local branches of the South African Institute
of Chemical Engineers (SAIChE), the South African
Institution of Mechanical Engineers (SAIMechE), and the
South African Institute of Electrical Engineers (SAIEE).
The event was a great success. Approximately 250
people from the four engineering institutions attended the
312
SEPTEMBER 1991
meeting with their wives and friends. Dc Mol spoke about
motivating people in the work situation and gave many
helpful, possibly controversial, but certainly challenging,
approaches for managers to motivate the people in their
charge. Dc Mol's talk was very well received, and a lively
discussion in the form of questions took place during his
talk and afterwards.
The function was a reasonable financial success, the
four institutions sharing the profits.
The Branch noted with grief the passing of a wellknown and renowned member of the Institute for 50
years, Mc D.D. McWilliam.
A joint meeting with the Institute of Refractories took
place on 18th October, 1990 at the Jan Smuts Airport Sun
Hotel. Dr MJ.U.T. van Wijngaarden, the guest speaker,
gave a presentation entitled 'Interaction of Metallurgy and
Refractories in Ladle Furnaces'. The meeting was very
well attended and was successful.
The second scholars' evening for Metallurgy in the
Vaal Triangle, which was held on Tuesday, 23rd April,
was co-hosted with the Vaal Triangle Technikon at their
Careers 2000 Exhibition during the week of 22nd to 26th
April.
The evening featured two videos on metallurgy, as well
as the same guest speakers who gave entertaining
presentations at the flfst meeting of this kind in the Vaal
Triangle in 1990: Professor David Horsfall and Professor
Gert Pienaar.
The evening was organized in conjunction with the
TED, DET, Iscor, and the Vaal Triangle Technikon. It
should have had a good attendance from Std 9 and 10
scholars studying maths and science at these levels in
both educational departments. The advertising among
scholars was left to the two representatives from the TED
and DET. The evening was again a large success, but the
audience was almost exclusively black. This was because
white scholars had not been reached by the advertising
campaign. A great deal of interest was shown by the black
scholars, and we can only hope that some of the attendees
will be attracted into our profession.
Iscor sponsored the refreshments, and the scholars had
the opportunity to speak to representatives of the mining
houses who were on duty at their stands at the Careers
2000 Exhibition.
As in previous years, the level of interest shown in the
Branch's activities by local members was disappointing.
The biggest single employer of metallurgical personnel in
the area is Iscor. This situation is enhanced by the decline
in the activities of the other major metallurgical player in
the region (USKO), following its recent poor financial
performance. Many of the senior metallurgists working
for USKO and who were, until recently, active in the
Branch's activities, have had to discontinue their
involvement owing to extreme work pressures. This has
been very sad for the region, and has taken its toll of local
interest
.
A meeting with Iscor personnel was held to promote
JOURNAL OF THE SOUTH AFRICAN INSTITUTE OF MINING AND METALLURGY
Branch activities among the metallurgists working for
this, the largest company in the area. The meeting was
fairly successful, but the harvest of interest can be gauged
only by the extent to which personnel from the
organization will participate in the Branch's activities
during the coming year.
The Branch kept visits to metallurgical companies
during workings hours to an absolute minimum-in fact
there have been no such visits-owing
to the lack of
response in previous years to this type of activity.
The decision to relocate the entire Engineering Faculty
of the Potchefstroom University has constituted a further
blow, and will limit future growth of interest in the area.

The Committee held seven meetings during the past
year and continued to focus its activities on creating an
awareness of the minerals industry in the region. In
particular, these activities involved mainly the Department
of Chemical Engineering at the University of Cape Town
(UCT) and the Department of Metallurgical Engineering
at the University of Stellenbosch (US). The Committee
also welcomed, in particular, the important contribution
made this year by Dr RD. Knutsen frol}l the Department
of Materials Engineering at UCT.
The Ninth Annual US/UCT Minerals Processing
Symposium was held at the Van Riebeeck Hotel in
Gordon's Bay on 3rd August, 1990, and was attended by
99 delegates. The Branch is grateful to SA Cyanamid,
NCP, Simon Carves (Africa), and the SAIMM for
sponsoring this event. The conference was preceded on
the evening of 2nd August by the Annual General
Meeting of the Branch, followed by the Annual Banquet.
We were privileged to have the President of the Institute,
Dc O.KH. Steffen, as guest speaker.
A Corrosion Seminar was held on 22nd March, 1991 at
UCT. This was a highly successful technical meeting and
was attended by 80 people. The main speaker was Dr
Stephen Lennon, Scientific Investigation Manager,
ESKOM.
One of the important functions of the Branch is to
generate interest in careers in the mining industry among
scholars in the greater Western Cape region. This year's
Schools' Day was held on 22nd April, 1991. As usual,
simultaneous programmes were offered at both UCT and
US. Once again, there was an enthusiastic response to the
invitation, 126 pupils from 26 schools attending the UCT
programme, and 84 pupils from 20 schools the Stellenbosch event.
During the 1991 mid-year university vacation, the
Branch is organizing, once again, a tour for Minerals
Processing undergraduates from both universities. This
year's tour will be led by Mc Jan Cilliers, assisted by Mc J.
Tucker, a Senior Technical Officer associated with the
Western Cape Minerals Processing Facility. This year's
visit will be to northern and eastern Transvaal mines.
The lOth Annual Minerals Processing Colloquium will
be held at Gordon' s Bay on 2nd and 3rd August, 1991.
Because of the success of this event over the past 10
years, the Branch has decided to expand the Colloquium
to a two-day meeting. At the same time, papers are being
called for from persons other than researchers at the two
local universities, although the emphasis remains that of
giving research students at the universities the opportunity
of presenting their current research findings to a critical
audience. So far, there has been an overwhelming
response to the call for papers, which will necessitate a
fair number of posters. There is every indication that this
conference will be an outstanding success. The plenary

This year the Branch was requested by Council to
arrange for the presentation of 50-year Membership
Awards to five members of the Institute currently residing
in our region, namely Messrs C.H. Coxton, O. Deane,
E.RC. O'Connor, J.S. van Zyl, and O. Weiss. Special
arrangements were made to present these medals to
Messrs Deane, O'Connor, and Weiss. The other
gentlemen have agreed to attend this year's Annual
Dinner to receive their medals from the President of the
Institute. All the members of the Committee were
involved in one or other of the presentations to the fIrSt
group of medallists, and all agreed that these were truly
memorable events. The gold medallists were unanimous
in their praise and gratitude to the Institute for the medals,
and the Branch congratulates Council on the introduction
of these awards.
The Branch thanks the Council of the SAIMM for the
excellent support it has enjoyed over the past year.
Although the Branch is far removed from the heart of the
mining industry, we believe that, through its teaching and
research functions, it is able to contribute significantly to
the activities of the Institute.

Mr Tom Schmoll, a member of the Committee for a
number of years, passed away in May 1991. He was serving as Branch Chairman at the time of his death, having
taken over from Mr J.A.D. Britz in April following the
resignation of Mr Britz from the Branch Committee.
On 25th September, 1990, 17 members and guests
attended a general meeting at Springbok Recreation Club.
Two papers were presented- 'Combating Corrosion with
Stainless Steel' by Dr 1. Fourie, and 'Review of
Kleinkopje Colliery Spiral Plant' by P. Henry.
Goedehoop Colliery hosted the meeting.
A total of 22 members and guests attended a visit to the
Stainless Division of Middelburg Steel and Alloys, during
which the entire stainless-steel process from 'melting' to
finished product was demonstrated. The general meeting
planned for 22nd May, 1991 at Bank Colliery was cancelled because of the death of Mr Schmoll.

5.1.1 Controlling Executive
Professor AN. Brown was inaugurated as President of
the AS&TS in November 1990. Relocation from Kelvin
House to the new site at Observatory was completed and
the office accommodation and meeting rooms were
renovated. Most of the available accommodation is
occupied and the meeting rooms are being well used. A
modest plan for development and improvement of the site
is being drawn up, and will be implemented progressively
as funds become available. However, the present
economic climate is not very favourable for the raising of
funds.
The AS&TS continued to experience difficulty with its
finances but now that renovations are complete and all the
Societies are established and settled, every effort is being
made to run the AS&TS profitably.
5.1.2 Science and Technology
The Learned Society Function was the subject of considerable debate during the year. Activities of the
Committee for Science and Technology form the core
function. It is perhaps understandable that these activities
received less attention and tended to be somewhat
neglected in the relocation to Observatory. However,
serious consideration needs to be given to the value and
usefulness of such activities, particularly in the present
strained economic climate. The matter has not yet been
satisfactorily resolved.
The AS&TS played a role as one of the organizers of
the World Environment Day Symposium, which was held
at Mintek on 5th June, 1991. The theme was 'Soil'. Attendance was smaller than in previous years. The SAIMM
nominee for the EPPIC Annual Award was successful.
The management of New Vaal Colliery received this
award in recognition of its work in environmental
planning, control, and rehabilitation under difficult
conditions.
Contact with the PROTEC programme
was
maintained, as was the connection with AFROTECH. The
latter is heavily dependent on funding from the private
sector, and its activities are currently restricted by limited
finances.
The AS&TS National Award was made to the Iscor
team for its ingenuity and perseverance in bringing the
new Corex steelmaking
process to a successful
conclusion. It is the first plant in the world to have done
so. The SAIMM nominated Iscor for this Award.

During the year under review, the Engineering Council
of South Africa (ECSA) came into being when Parliament
passed the Engineering Profession of South Africa Act
(Act No. 114 of 1990). On 18th April, 1991, the functions
of the South African Council for Professional Engineers
(SACPE) and the three Boards of Control (for
Professional Technologists, Registered Certificated
Engineers, and Engineering Technicians) were taken over
by ECSA.

OF THE SOUTH
AFRICAN
INSTITUTE
S.3 The South African Engineering
Association (SAVI)
Representative
RD. Beck
Alternate
Dc O.K.H. Steffen
After a long series of discussions between representatives of the professional institutes and vocational groups,
a draft constitution for the South African Engineering
Association (SAVI) was drawn up, and the Association
was formed in May 1989. A representative of the SAIMM
was party to these discussions, and Council debated issues
raised on a number of occasions. The concerns raised by
the Institute were not wholly addressed.
The SAIMM supported the aims of SAVI, which are
defined in the Association's constitution as follows:
(a) to advance the status and image of engineering;
(b) to further co-operation, communication and unity
among the engineering profession;
(c) to strive for improved engineering education and
training, and to promote careers in engineering for all
South Africans;
(d) to promote liaison with other national, regional and
local authorities, and the public;
(e) to advise and act on matters of policy and legislation
that affect engineering as a whole at national level.
The Council could not recommend joining SAVI for the
following reasons.
SA VI has an agreement that membership of SA VI
requires compulsory membership of the Society for
Professional Engineers (SPE). The principle that joining
of vocational groups must be individually voluntary is
strongly upheld by the SAIMM. In addition, the
majority of the objectives of SPE are already covered by
the Institute.
The weighted vote based on members of the Institutes
.
.
.
was not acceptable to the SAIMM.
Other minor problem areas, including the budget, were
cause for concern.
In view of the important initiatives being taken by SAVI
in the field of education, the SAIMM felt that the Institute
should accept SAVI's invitation to attend meetings of the
SAVI Council and negotiate changes that the SAIMM felt
were necessary if it was to join SAVI.
The issue of compulsory membership of SPE was delinked from SAVI, and membership of that vocational
group is now a separate issue. A new weighted vote was
negotiated and accepted by SA VI and the SAIMM
Council.
In February 1991, the SAIMM Council decided that the
SAIMM would join SAVI after the necessary changes had
OF MINING AND METALLURGY
SEPTEMBER 1991
315
been made to the SAVI constitution. These changes were
being made at the time of the writing of this report.
The SAIMM has expressed concern at the structures in
which SAVI operates in relation to member institutes and
vocational groups, but believes this issue will best be
dealt with when it is a full member of SAVI.
The following issues were dealt with by SAVI during
the year.
Education
In response to the concern about the decline in the
numbers of people entering the engineering profession
and the conviction that a strong engineering profession is
required for the future development of South Africa,
SAVI developed the concept of the National Foundation
for Technological Development (NFTD). This concept
was refined in negotiations with major employer bodies,
the Government, and industry.
The initiative was submitted to the Economic Advisory
Committee (EAC) of the State President in September
1990. While receiving overall support, the document was
rejected on the grounds of the concern expressed by the
EAC that it would involve the establishment of yet
another bureaucracy. SAVI was requested to rethink its
desire to establish a separate body and to identify ways of
inter- acting with an existing government body.
To this end, the newly structured Foundation of Research Development (FRD) was identified as being a
suitable vehicle. Discussions were held with the FRD and
the basis for a partnership was decided upon. The details
were submitted to the EAC in November 1990. The
document was accepted, with one slight modification, in
the hope that the EAC would retommend to its executives
that the concepts were of sufficient importance to receive
the highest attention within Government.
The major objectives of the education initiative are to
create closer links between technikons and universities in
an attempt to optimize resources, provide for adequate
staff interchange and, finally, to ensure a sufficient output
of suitably qualified graduates and diplomates.
Furthermore, it is seen to be vitally important that
cognizance should be taken of the important assistance
that tertiary engineering educational institutions can give
the country by providing the necessary man-power skills
for uplifting the economy.
A fifteen-man board comprising the FRD, industry,
and SAVI has been formed to act as a Controlling Board
to carry these objectives forward. The minerals industry is
represented by Mr AH. Munro, FSAIMM, acting for the
Chamber of Mines.
Technology Strategy
The document on Technology Strategy from the
Department of Trade and Industry and the draft Strategic
Document on Technology published by the ANC were
examined and commented on by SAVI.
316
SEPTEMBER 1991
Unification of the Engineering Profession
SA VI continued to express concern that the South
African Institution of Chemical Engineers (which
withdrew from SA VI over the same issues as the
SAIMM) and the SAIMM were not members of SAVI.
With the changes already reported, both have indicated
that they will join SAVI.
SAVI Think-tank
On Saturday, 26th January, 1991, members of the
SAVI Council and Presidents of the Institutions were
invited to participate in a one-day SAVI Think-tank. The
current structure of SAVI was discussed, as well as the
role of the vocational groups, issues relating to the
administration and financing of SAVI, and other projects
that were deemed to be important for the future wellbeing of the engineering profession in the country. It was
concluded that SAVI should take an active lead in the
promotion of technology,
in forging links with
international engineering org- anizations, and in setting up
a major campaign to try to inform the public of the
importance of technology.
Relationship with ECSA
An important feature of the deliberations of the SAVI
Think-tank was the relationship with the new Engineering
Council of South Africa (ECSA). While it was recognized
that each body has a specific role to play in terms of the
constituency to which it must report, it was thought that
there are a number of areas in which a combined approach
might be more beneficial. It was unanimously agreed that
co-operation would only strengthen the engineering
profession and, in particular, could lead to rationalization
and reduced costs. Both parties committed themselves to
this goal.
Relationship with the Scientific Community
One of the areas of concern expressed by the SAIMM
has been about the future of the AS&TS as a learned
society. The strength of SAVI has been seen as a potential
threat to AS&TS. SAVI has recognized the importance of
closer ties between the engineering and scientific
professions. The SAIMM has expressed its conviction
that the AS&TS should exert itself as the key player in
forging these links.
In conclusion, the arena provided by SAVI to enable
representatives of the various fields in the engineering
professions to meet, discuss, and take up issues of
common interest is seen as an exciting development for
engineering. The SAIMM is actively contributing to this
development.

required. The new Engineering Profession of South Africa
Act, 1990 (Act No. 114 of 1990) was promulgated in
1991. This document has been studied carefully by the
Committee, and a summary of the 'Role and Implications
of the New Act' will be published in the Journal shortly.

Registered Engineering Technicians (ASARET)
Representative

Dr J. Lurie
The historic inaugural meeting of ASARET took place
on 18th September, 1990 at Megawatt Park. ASARET
was constituted in order to fulfil the requirements for the
vocational body to represent the interests of engineering
technicians. As such, it is a society of individual members,
as opposed to an affiliation of societies (as was ASRET,
which it replaces). The latter organization will be
disbanded in due course.
SAIMM has become a patron member of ASARET in
order to ensure a continuing input from the learned
society. Dr J. Lurie was elected to the Council of
ASARET and also appointed as the Council representative
on the SPE/SA VI Education Committee.
Approximately
600 applications (representing a
number of engineering disciplines, including mining and
m~llurgy) were received for individual membership in
response to the first circular letter to registered
engineering technicians.
An initiative has commenced whereby technicians in
the mining and metallurgical fields will be ertcouraged to
register with the Engineering Council of South Africa
(ECSA) and to join ASARET.
5.6 South African Association of Registrable
Engineering Technologists (SAARET)
Representative
Dr J. Lurie
The Executive Committee and Education and Training
and Publicity Sub-committees held monthly meetings
during the period.
A highly successful Autumn School, organized jointly
by SAARET and the Student Mechanical Engineers
Association, was held during April 1991 at the Technikon
Witwatersrand.
The SAARET award for the most outstanding Master
diploma student in an engineering discipline was awarded
to Mr A. Oosthuizen, a Mechanical Engineering student of
the Vaal Triangle Technikon.
The future format in terms of duration, experiential
training, and investigative
projects for the formal
educational qualification of the technologist at technikons
was considered widely in the engineering world and also
by the SAARET Education and Training Committee. So
far no consensus has been reached.
Profiles of mining and metallurgical technicians and
technologists were submitted by working groups. That for
the chemical engineering technician is complete, but that
for the technologist is still being considered.
5.7 Engineers' Liaison Committee
Representative
Prof. AN. Brown
Mr W.F. Cronje was re-elected Chairman, and the
Committee met under his leadership. The Hendrik van der
Bijl Memorial Lecture is usually presented in May, but the
29th Lecture will be presented in September 1991 by Mr
Gert van der Veer, Chief Executive of SA Airways. The
Annual Social Function in November was to be held at the
CSIR's new wind tunnel, but unfortunately had to be
cancelled.
5.8 Programme for Technological Careers (PROTEC)
The SAIMM continued to support PROTEC by way of
a grant PROTEC provides support for black students in
high schools, and has a number of branches throughout
South Africa, each of which is subsidized by local
industry. The number of PROTEC students grew from
4166 to 6098 in 1990/91. The pass rate for the 1990
matriculants was 75 per cent, of whom 39 per cent
obtained exemption (university entrance) in maths and
science.
The above statistics compare very favourably with the
national figures for black students. This was achieved
despite the ongoing disruption
of life in black
communities and dangerous conditions for staff. Saturday
classes were offered at most branches to assist students in
catching up on lost time. In some cases industry helped
with laboratory facilities and visits.
More than half of the PROTEC matriculants have taken
up careers in engineering and science.
5.9 Phoenix National Committee
Representative
Dr B.K. Loveday
Alternate
Dr RH. Eric
The Phoenix Fund is administered by the SAIMM, and
daily activities and projects are carried out by staff in the
Educational Department of the Chamber of Mines of
South Mrica (COM). During the early part of 1990, the
Education Advisory Committee of the CaM, which
includes education specialists drawn from individual
mining groups, examined the country's education system
and formulated an overall education policy for the mining
industry.
This policy spells out the Chamber's standpoint on the
requirements
of an adequate system. The CaM's
Education Mission is:
to be actively involved in the development
.
of a relevant
and legitimate national education system, which will
encourage optimum economic growth and ensure an
optimum flow of appropriately educated persons into
industry, and the mining industry in particular.
JOURNAL OF THE SOUTH AFRICAN INSTITUTE OF MINING AND METALLURGY
SEPTEMBER 1991
317
After the formulation of the education policy, it
became clear that the promotion of careers in the mining
industry and direct recruiting into the industry was a
mining-group matter. Consequently, during the latter part
of 1990, liaison with schools and other careers-related
types of activities were discontinued. Cost pressures also
encouraged rationalization and the focusing of activities
and resources. This resulted in the rationalization of all
the education activities of the CaM into one Education
Department. This Department now concentrates on
activities such as the Phoenix programme, Bursaries,
Tertiary Education, Support Programmes, and Education
Policy, as well as advice, liaison with other education
stakeholders, promotion of education policies, and general
education administration.
Following the rationalization of all the education
activities, Mr Demmer was appointed to manage the
Education Department, and to report to the Chamber's
General Manager, Education Services. During January
1991, Mc K. McCarogher took control of all aspects of the
Phoenix programme, with two members of staff to assist
him with daily activities. Secretarial and administrative
back-up is provided by staff in the Chamber's Education
Department.
In consultation with the mining groups, a major thrust
of new activities was planned under the expansion of the
programme. Expansion is aimed primarily at physical
science teachers and physical science lecturers at the
black colleges of education.
The CaM is the major financial sponsor of the
programme, which is jointly administered by the Chamber
and the SAIMM.
The main goals of the programme for 1990/91 are
listed below:
to provide in-service training and support for science
teacher/educators (lecturers) at colleges of education on
a national basis;
to develop and implement science resource material that
relates mining and minerals processing to concepts in
the science syllabus for science teachers; this will
include the optional science topics on manganese and
copper and on two packages on gold and coal which are
currently being developed;
to influence education departments and planners of
syllabi and curricula to include a better representation
of the minerals industry in new science and geography
syllabi;
to participate in the debate on the formulation of an
education policy for school science in South Africa.
.
.
.
.
During January 1991, an extensive one-week
workshop, the third of its kind, was conducted in
conjunction with the University of the Witwatersrand for
75 college lecturers from black colleges of education. The
black colleges of education train the majority of
318
SEPTEMBER 1991
mathematics and physical science/general
science
teachers in South Africa. The content of the workshop
activity was designed to upgrade the academic skills of
these teacher/educators
(science lecturers) in both
chemistry and physics. The workshops addressed
science/technology/society
issues that are in the new
college of education syllabi. In consultation with the
college lecturers, several workshops have been planned
from July 1991 to July 1992. These will focus on upgrading their academic and practical skills.
The optional science topics resource packages on the
chemistry of copper and manganese were completed in
1990. These packages have been extensively introduced
into schools. In the second quarter of 1991, Phoenix staff
conducted 24 one-day courses for science teachers from
Transvaal schools. In one six-week period, 580 science
teachers attended these courses in Pretoria.
An additional two packages are being developed (and
trial-tested in the classroom) on the chemistry of gold and
coal. The fIrst drafts of these packages should be completed at the end of 1991; trial-testing in the classroom will
begin during the early part of 1992. These packages will
be tested extensively in schools before they are printed in
final draft form.
This type of science material, which relates mining and
mineral-processing techniques to the school science syllabus, has been extremely well received by science teachers throughout South Africa. It forms part of an ongoing
process to make science in the school classroom more relevant to its applications in everyday life. Such packages
are following trends in other areas in the world where this
type of material is making science and technology relevant
to its daily usage.
Staff on the Phoenix programme have been closely
involved with a project team working under the guidance
of the School of Science Education at the University of the
Witwatersrand to produce guides for science teachers
from Std 2 to Std 10. The fIrst science teachers' guide (Std
5) was completed in July 1991; it will be launched at the
National Science Teachers' Convention in Cape Town.
The authors of these science teachers' guides are currently
negotiating with an international publisher to produce sufficient copies for all science teachers throughout South
Africa.
The Phoenix Programme has continued to maintain
contact and liaison with other organizations, both formal
and informal, whose primary aim is to promote science
education in schools and to encourage scholars to pursue
careers in engineering, technology, and the earth sciences.
The CaM and the SAIMM are extremely grateful for the
financial support received from the following companies
and organizations during 1990: AECI, Mintek, Envirotech,
Ferro Alloy Producers' Association, Haggie Rand, Iscor,
Rio Tinto South Africa, and Sasol.

SAIMM has been a constituent member of EPPIC for
many years.
Since the promulgation of the Environmental Conservation Act (Act No. 73) in June 1989, EPPIC's role has
become increasingly important. EPPIC's perception of the
function it sees for itself in terms of its Strategic Plan is as
an intermediary between Central Government and the
professions and professionals.
The status of EPPIC has been augmented by the
approach made by the Council for the Environment to
disseminate the philosophy of Integrated Environmental
Management (IEM) throughout South Africa via its
constituent Institutes and EPPIC's Regional Groups.
!EM is a systematic approach to ensure the stiuctured
inclusion of environmental considerations in decisionmaking at all stages of the development process.
EPPIC has representation on the Environmental Impact
Assessment Sub-Committee
of the Committee for
Environmental Management under the Environmental
Conservation Act, and presented its views on its future
role to a Committee of the President's
Council
investigating a National Environmental Management
System. EPPIC is increasingly being requested by the
Depanment of Environmental Affairs to comment on draft
documents.
The Council for the Environment has suggested that
EPPIC should request its constituent Institutes to develop
project-specific
procedures that incorporate IEM
principles and to let the Council know (through EPPIC) of
any problems they or their members are experiencing in
the implementation of !EM. Any contribution would be
welcomed, and should be addressed to the SAIMM for
submission to EPPIC.
EPPIC is currently re-surveying the availability of
environmental education at tertiary level. A report on the
results of this survey will be available in due course.
EPPIC recognizes sound environmental planning and
management through its National and Regional Awards,
which are presented at the World Environment Day Symposium in which it participates each year. This year the
SAIMM was again successful with its nomination. New
Vaal Colliery received EPPIC's National Premium Award
at the Symposium held on 5th June, 1991.
In May, EPPIC held the flfst of what it intends will
become a series of prestigious annual environmental
conferences. The theme this year was that important and
scarce resource in our country-water-and
how it should
be managed for sustainable use. The conference was
opened by Dr Louw Alberts, Chairman of the CSIR. Some
150 delegates attended. The standard of papers was
excellent, covering a wide range of aspects of water,
including the potential for its pollution from mining
operations.
EPPIC has prepared and makes available to its
members various publications. Currently available are the
Guidelines for Public Participation in Environmental
Planning and Decision-making and a summary of the
implications of the Environmental Act (Act No. 73 of
1989) as it affects the planning professions.
These publications and more information about EPPIC
and its Regional Groups are available from the Secretary,

the SAIMM
at a
6.1.115th CMMI Congress
National Representative Dr H. Scott-Russell
The Council of the CMMI agreed that the 15th
Congress would be hosted by South Africa in 1994 during
the centenary year of the SAl MM. An Executive
Committee, including representatives of the mining
industry and the Geological Society of South Africa, has
been convened to start organizing this Congress, which
will be hosted jointly by mining-industry organizations. It
is intended that the whole of Southern Africa should be
involved in this Congress.
6.2 World Mining Congress
National Representative Dr H. Wagner
The International Organising Committee of the World
Mining Congress held meetings in New Delhi, India, and
in Madrid, Spain. Unfortunately, it was not possible for
the South African members of the International
Organising Committee to attend those meetings. The
arrangements for the 15th World Mining Congress, which
is to be held in Madrid, Spain, from 25th to 29th May,
1992, are well advanced. In parallel with this Congress,
there will be an International Mining Exhibition.
One of the international projects of the World Mining
Congress is the publication of updated mining and
mineral statistics. South Africa continued to provide the
relevant infonnation.
6.3 APCOM '91
National Representative Prof. D.G. Krige
The 22nd APCOM Symposium was held from 17th
September to 21st September, 1990 in the modem ICC
320
SEPTEMBER 1991
JOURNAL
Conference Centre in West Berlin. The facilities, which
were excellent, included the simultaneous translation of
all proceedings into English, Gennan, and Russian. The
two main sponsors, the Technical and the Free
Universities of Berlin, as well as the Stenkohl Research,
the German Research Society, the Political Senate of
Berlin, and the German Academic Exchange Service, are
to be congratulated
on their organization
and/or
contributions, financial or otherwise.
As has become customary at APCOM meetings, the
social side and the programme for the forty-odd affiliates
were all of a high standard, as were the workshops and
tours to mining, metallurgical, and other venues.
There were 389 registered participants from 35
countries, of which the two with the largest number of
delegates were Gennany (163) and South Africa (31). The
major regions of Western and Eastern Europe, North and
South America, Africa, the Middle and Far East, and Australasia were all represented. A feature of this symposium
was the enthusiastic participation of Eastern Europe from
which there were 80 registrations, i.e. over 20 per cent of
the total number.
A total of 425 abstracts was received, which had to be
reduced to the final 169 papers published. The topics
covered were the usual, particular emphasis being laid on
mining and also on computer-aided design (CAD) and
expert systems. Mineral processing and exploration could
have received more attention.
Of particular importance to South Africa and the
SAIMM was the election of Professor Danie Krige as the
new Chainnan of the International APCOM Council; he is
the fIrst non-USA member to occupy this position.
The next APCOM is being organized by the University
of Arizona, and will be held in Tucson from 7th to 11th
April, 1992.
6.4 INF ACON '92
NatiOl1ll1Representative Dr RE. Robinson
The sixth International Ferro Alloys Conference, which
is to take place from 9th to 12th March 1992, is being
jointly organized by the SAIMM, Mintek, and the Ferro
Alloys Producers' Association.
Arrangements by the Organizing Committee, under the
chainnanship of Dr Robinson, are proceeding well and the
Committee is about to issue the final circular for the
registration of delegates. The Conference is to be held in
Cape Town, and the focal point will be the conference
centre at the Cape Sun Hotel. The response to the first
circular was disappointing, and urgent attention was given
to the distribution of a second circular with a wider
circulation. Responses to this second circular are still
being received, and have exceeded all expectations. It is
still not unlikely that over 500 delegates will be present. A
large contingent is expected from overseas.
This will make Infacon one of the most prestigious
conferences to be held in South Africa, but will also strain
the accommodation facilities in Cape Town to the limit. It
OF THE SOUTH
AFRICAN
INSTITUTE

is hoped to run the International Conference on Chromium
and Stainless Steel, also being organized by the SAIMM,
concurrently.
The Institute will have the responsibility of publishing
the proceedings of the conference.
7.1 Forward Planning
The technical programme of the Institute continues to
operate on a four-year pIan to ensure that the activities of
this Institute are co-ordinated with those of other societies
serving the mining industries in South Africa and abroad.
6.S International Chromium Steel
and Alloys Congress (INCSAC)
National Representative 1.P. Hoffman
The above-mentioned Congress will be held in Cape
Town from 8th to 12th March, 1992, in conjunction with,
and parallel to, Infacon '92.
The Congress is being organized by the SAIMM, and
will provide a forum for engineers, technologists,
scientists, fabricators, and managers who are concerned
with the production and application of chromium steels
and alloys.
INCSAC '92 will focus on new developments in
process metallurgy, physical metallurgy, and the
production and application of chromium-contained steels
and alloys in corrosive, abrasive, and elevatedtemperature applications.
Some 50 papers, including those of invited, specialist,
and keynote speakers, each an expert in his field, will be
prd'ented. Some of these speakers will be from overseas.
Delegates will also be given an opportunity to attend a
joint session with Infacon delegates on chromium and
chromium alloys.
Delegates from 23 countries are expected to attend the
Congress. Early-bird registration forms are expected back
by 30th November, 1991.

Portfolio
AND ADMINISTRATION
Holder:
H.G. Mosenthal
Our new office accommodation in Cape Towers is
proving most satisfactory. All meetings apart from the
Council meeting are held in the two committee rooms.
The Council meetings are convened in the nearby
Chamber of Mines Building.
Council members and the Secretariat contilJued to liaise
closely. The following staff are employed in servicing the
needs of the Institute and its members: Mrs C. Mackintosh
(Manager), Mrs P. Smith, Miss C. lansen, Mrs S.
Moodley, Mrs K. Norman, and Mrs A. Panana. Our
congratulations to Council member, Peter Smith, and Miss
Pam Binstead who were married during the year.
With the withdrawal from typesetting of Mrs Claire
Keamey, it was decided that a desk-top publishing system
should be purchased and additional staff employed to
undertake the typesetting of our Journal and bookpublications section internally.
It was with regret that Council accepted the resignation
of our Treasurer, Dr H. Wagner. He will be replaced in the
1991192year by Mc I.A. Cruise.

The Institute experienced a difficult financial year and
recorded a loss of R63 153. This loss can be attributed to
the following main causes.
(i) The income from colloquia and schools was lower
than in previous years. This was because fewer events
were organized and because of a drop in attendance
figures, which can be attributed to the economic
difficulties encountered by the industry.
(ii) The production costs of the Journal markedly
exceeded the budget, and account for most of the loss
incurred by the Institute.
Steps have been taken to address these problem areas.
The technical programme has been reviewed, and the
emphasis is being placed on one-day events to keep costs
to the industry Iow. The method of producing the Journal
has been reviewed, and should result in substantial costsavings in the future.
As in previous years, the value of the stocks of books
and medals is shown, on the insistance of the auditors, in
the accounts at a nominal figure ofR5.
The book value of the Institute's
investments
decreased by R133 569. The decrease was caused by two
factors. Firstly, in close consultation with the Institute's
investment advisers, the investment portfolio was restructured to account for some major changes that have
taken place in the investment sector. Some low-yielding
investments were sold at a loss. Secondly, the Chamber of
Mines of South Africa, which administers the Phoenix
programme, withdrew RHO 000 from the Phoenix Fund
to fmance a computerization programme. Accordingly, the
Institute was forced to sell some of its investments at an
inappropriate time. Despite these facts, the market value
of the investments increased from RI 565 825 to RI 743
225, reflecting a satisfactory
performance of the
investment portfolio. The total performance of the
portfolio was 18,7 per cent compared to the performance
of the overall share index of 7,4 per cent, and the unit trust
index of 12,3 per cent.
As in previous years, most of the investment income
was re-distributed to the various funds that are operated
by the Institute to maintain their value in real terms. In
line with this policy, an amount of R38 500 was
transferred to the various funds.
Despite the financial difficulties, it was decided to
keep the increases in membership subscriptions below the

level of inflation. This decision was taken in line with the
Institute's policy of financing its operation, as far as
possible, through activities in the field of technical
programmes and publications.
Thanks are due to Martin & Company, who continue
to act as the Institute's
financial advisers; to the
secretaries for their efforts in containing costs; and to the
accountant and auditor for excellent services rendered
during the year.
