Nov 17, 2020· 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 electrochemical half reactions.
