Electrowinning an overview ScienceDirect Topics

Electrowinning is the plating of metallic copper from the CuSO 4 H 2 SO 4 H 2 O electrolyte produced by solvent extraction. It consists of passing direct current between inert but conductive anodes (usually PbSnCa alloy) and stainless steel (sometimes copper) cathodes. The cathodic copper deposit is similar to that from electrorefining.
