  • Electrowinning Metallurgist & Mineral Processing Engineer

    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 The cathodic reaction is: Cu++ + 2eElectrowinning is used to recover copper from leach solutions containing more than approximately 25 g/L of copper (Harlan process) The electrolytic cells are equipped with insoluble lead–antimony anodes and 99% Ni cathodes The copper powder deposits do not stick and gravitate to the bottom of the cells The temperature of the electrolyte is maintained at 60°C; cathode current varies fromElectrowinning an overview | ScienceDirect Topics
