Short course in Geneva, 23-25 April March 2003
Ore Dressing and Environmental Geochemistry of Mine Waste Management
by Dr. Rainer Lehne, Heidelberg and Dr. Bernhard Dold, Lausanne
A) Ore dressing (Dr. Rainer Lehne, Heidelberg) Wednesday 23 and
morning of Thursday 24
- Gold ores and their metallurgical treatment (gravity processes,
amalgamation, flotation, leaching...), gold extraction, cyanide
leaching
- Microscopy of gold ores and their treatment products (practical exercises)
- Base metal ores and their beneficiation . Flotation.
- Microscopy of base metal ores and milling products
- Specific tasks of microscopical investigations
- Microscopy of selected base metal ores and milling products
(practical exercises)
B) Environmental Geochemistry of Mine Waste Management (Dr. Bernhard
Dold, University of Lausanne), afternoon of Thursday 24 and Friday 25
The short course focuses on the geochemical reactions associated with
the management of wastes from mining and milling operations. Topics
will include a review of aquatic chemistry, a summary of the
environmental geochemistry of ore deposits, chemical and biological
transformations in mine and mine waste environments, and application
of these principles to understanding water quality problems in
tailings disposal facilities, pit lakes, waste rock piles, and mine
drainage. Special attention will be directed towards addressing
problems associated with acid solutions resulting from mining
activities in sulfide formations.
Registration by e-mail to [log in to unmask] until April 4, 2003.
Places limited (15).
