There are two main methods of refining gold—the Wohlwill process or the Miller process. The Wohlwill process was invented in 1875 by Emil Wohlwill and produces gold to a high degree of purity (99.999 percent). The Wohlwill process is an electrochemical process. The Miller process produces a slightly lower purity of gold, only 99.95 percent pure.
Apr 24, 2017· Another large-scale gold refining technique, the Wohlwill Process refines gold to 99.999% purity — the highest purity possible. Developed by Emil Wohlwill in 1987, this electrochemical process uses a 95% pure gold bar as an anode and small sheets of pure, 24-karat gold as the cathode.

The diagram gives an overview of the key processes involved in the refining of gold and silver. Please note that this is highly simplified and does not detail the many sub-processes involved within each key process, the chemical inputs involved in each process, as well how the waste outputs from each process are handled.
A naturally occurring alloy of gold and silver is known as electrum. Other gold minerals are rare. Gold is commonly associated with the sulfides of antimony, arsenic, copper, iron, and silver.3 B. Generalized Proc ess Description Precious metals may be recovered from the ore or from refining processes of base metals such as copper and lead.
Jul 15, 2020· The 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 gold.
