Electrowinning cells are used for the production of a number of primary metals such as Cu, Zn,Ni, and Al. Electrodeposition cells are used for depositing small quantities of metals on to a substrate for altering their surface properties such as increasing corrosion and abrasion resistance, or simply for aesthetics, as in the gold plating of silver

Electrowinning - Metallurgist & Mineral Processing Engineer

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 + O2 + H2SO4. The overall reaction is the combination of two electrochemical half reactions.
