ntternational Conference in
n
Many countries are experiencing an increasing
interest in exploring for and exploiting minerals..
But in mining projects a main challenge is to
manage mine tailings and waste rock in a
manner that will be environmentally acceptable
and work essentially in perpetuity. Often,
land-based solutions have been preferred, but
these may require maintenance for unpredictable time periods after mine closure, and several
instances of dam failure illustrate that landbased disposal can be problematic. Submarine or
lacustrine disposal of waste may in some cases
offer better opportunities to secure long-term
solutions.
The objective of the conference is to gather
specialists from the mining sector and the
scientific and regulatory communities to present
and discuss advantages and disadvantages of
placing mine tailings and waste rock in the sea
or in lakes. What criteria should be used if we
are, for example, to create stable submerged
deposits and minimize the risk of extensive
smothering of the sea bed, the risk of uncontrolled dispersal of fines and the risk of release
of contaminants? What baseline studies are
needed?
The organizers encourage presentations of case
studies from closed and existing mines and from
those in the planning stages. Each speaker will
be asked for an abstract to be sent to the
conference together with the registration. We
will not publish proceedings of the conference,
but intend to make a written report with the
main conclusions and recommendations, based
on the presentations and the discussions.
Presenters will be requested to make their
Powerpoint presentations available as an aid to
the preparation of the meeting report. Among
the participants the conference organizers will
appoint members of a group that shall report
the main findings, conclusions and recommendations from each session. The conference will be
relatively small with a maximum of 70 participants, with appropriate time for both presentations and discussions. The organizers reserve the
right to select from among the proposed
presentations and participants when preparing
the final program. The conference language will
be English.
