Chapter 12 Energy Efficiency of Electrowinning
Prior to electrowinning, the metal is placed into solution by leaching of ore or concentrate. The leachate is then, often, processed to concentrate the target metal ion and reduce deleterious impurities. It is important to recognize that elec-trowinning is often the end of a series of chemical processing steps.
