Copper Electrowinning In Zambia
A Bright Future for copper electrowinning | JOM
Over the past 40 years, the copper mining industry has undergone a dramatic shift toward hydrometallurgical extraction of copper at the mine site. This has increased the importance of recovering high-purity copper by electrowinning. High-purity cathode production was achieved by implementing numerous technologies including superior lead-alloy anodes, …

Metal Recovery Processes
Cathode quality is more difficult to control in zinc electrowinning than it is in copper electrowinning. The standard zinc potential (−0.763 V) is lower than many of the impurity metals that can be found in zinc electrolyte solutions. Despite the difficulty, 80% of the primary zinc production is derived by electrowinning .
