The Keynote Address at the Nickel-Cobalt Dinner was given by David Dreisinger, Professor and Chairholder, Industrial Research Chair in Hydrometallurgy, the University of British Columbia, Vancouver, Canada and President, Dreisinger Consulting Inc. who spoke on “Hydroprocessing of Sulphides – Where Are We and Where Are We Heading”. The Nickel-Cobalt-Copper Sessions included a Forum and Panel Discussion on Hydroprocessing of Sulphides which included papers on bio, pressure, galvanic and chloride leaching. Other topics included processing of laterites, laterite projects, process technology, electrowinning, SX/IX, cobalt recovery and equipment and materials. A highlight was Eramet’s paper on their Weda Bay Project, Indonesia, for which they have developed an atmospheric leaching based process.

The featured Forum and Panel Discussion in the uranium sessions focused on Uranium Heap Leaching. Other topics presented included SX/IX, uranium ore leaching, and project development.
