— Electrolytic refining. This method gives the highest-purity metal product as well as the best recovery of valuable impurities. It is used for copper, nickel, lead, gold, and silver. The metal to be refined is cast into a slab, which becomes the anode of an electrolytic cell; another sheet of metal is the cathode.

Electrolytic recovery of copper from copper-zinc sulfate solutions obtained by hydrometallurgical treatment of brass ashes and flue dusts has been studied by Duman et al. (1989). It was revealed that Zn 2+ ions cause grain size reductions of the cathodic copper in relatively high copper electrolytes.

Electrolytic refining. The purification uses an electrolyte of copper(II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper(II) ions are deposited as copper. At the anode, copper goes into solution as copper(II) ions.
