Electrolytic Refining of Gold
The method just described aims at leaving gold in an insoluble state at the anode Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution The active agentThe two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified goldProcessing, smelting and refining gold | World Gold Council
