Electrorefining of Copper

Virtually all copper produced from ore receives an electrolytic treatment at some stage either via electrorefining from impure anodes or electrowinning from leach or solvent- extraction liquors. Electrorefining produces the majority of cathode copper ca. 95% as opposed to ca. 5% from electrowinning). The electrorefining step serves two purposes: 1) Elimination of unwanted impurities;
