The Solvent Extraction Electrowinning Recovery of Zinc

The Eskay Creek orebody is located in north-central British Columbia (Canada). The ore contains major gold and silver values and minor but economically significant quantities of zinc. The refractory nature of the gold necessitates a pressure oxidation pretreatment prior to cyanidation. After solid-liquid separation the oxidation solution can be treated by oxyhydrolysis for iron removal...
