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 electrochemical half reactions. The cathodic reaction

Electrowinning - an overview ScienceDirect Topics

Typical of electrowinning from aqueous solutions is copper electrowinning. The electrolyte entering the cells contains 25–60 g l -1 of copper, 50–180 g l -1 of sulfuric acid, and 5–10 g l -1 of iron salts (Habashi, 1998). It is produced by leaching of copper ores, with solution purification by solvent extraction.
