Improved anode and cathode processes in base metal electrowinning

Summary

The outcomes of this project include a review of alternative anode materials, and results of tests on physical and chemical properties of many anodes supplied by project sponsors.

The report also includes results of studies on the corrosion of anodes for electrowinning of copper and zinc and effects of additives on corrosion rates, and describes aspects of the cathodic processes affecting the quality of copper and zinc cathodes.
