Electrowinning. Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4. The overall reaction is the combination of two ...

Introduction. The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.
