Anodes of alloys, which may be fragmented and used in baskets, of passive filmforming metals and elements having atomic numbers 2329 for use in electrowinning metals, methods of using such anodes, and electrowinning cells incorporating such anodes.

Electrowinning is the process whereby metals, such as gold, are recovered from concentrated solutions by applying a voltage across electrodes immersed in the concentrated solution. The voltage applied across the electrodes (hode and anode) results in a hodic reaction which in turn results in the deposition of the metal from .

Request PDF on ResearchGate | Effect of Silver Content in PbAg Anodes on the Performance of the Anodes During Zinc Electrowinning | The efficiency of the electrowinning process of zinc depends on the performance of oxygen evolution reaction, anode quality and corrosion resistance of lead anodes.

Conventional leadbased anodes used in the zinc electrowinning are associated with high corrosion rates and oxygen evolution overpotential in the electrowinning process. These result in some problems such as Pb contaminating the zinc hode, shortened anode lifetime, and high energy consumption in the process.
