    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.

    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++ + 2e
