Electroextraction
Electrowinning produces pure metallic copper from leach/SX electrolytes. In 2010, about 4.5 million tonnes of pure copper were electrowon. Electrowinning entails applying an electrical potential between inert Pb-alloy anodes and stainless steel (occasionally copper) cathodes in CuSO 4 –H 2 SO 4 electrolyte. Pure copper electroplates on the
