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 Pb–Sn–Ca alloy) and stainless steel (sometimes copper) hodes. The hodic copper deposit is similar to that from electrorefining.
