The electrolyte is copper sulfate (0.7 molar) and sulfuric acid (2 molar) and the way in which the purification of the copper occurs can be seen by considering the metals likely to be found. as impurities : 3) Ag, Au and Pt are more noble than copper and therefore will not dissolve anodically. They will be found as metals in the anode slime;

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) cathodes. The cathodic copper deposit is similar to that from electrorefining. Industrially, the electrodes are about a square meter
