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. A number of developing projects were presented including UraniumSA’s Samphire Project in South Australia, Toro Energy’s Wiluna Project in Western Australia, Greenland Minerals and Energy’s Kvanefjeld Project in Greenland, Aura Energy’s Häggån Project in Sweden and A-Cap Resources’ Letlhakane Project in Botswana.
