Energy Efficiency of Electrowinning
The winning of high purity metal from aqueous solutions through electrodeposition is the final processing recovery step for many nonferrous metals. Direct electrical current/voltage provides the necessary driving force to promote the necessary reactions at an industrially relevant rate. Energy, especially electrical, is often the highest cost for electrowinning operations. Therefore, energy efficiency is a paramount concern for modern facilities. This chapter discusses electrical energy consumption in aqueous electrowinning with a specific focus on cell voltage and current efficiency. It also presents potential improvements.
