Before a process can be chosen, the gold meant for refinement has to be evaluated for gold content. Once the amount of gold contained has been established, refining can begin. The Wohlwill and Miller processes are the two main methods used to refine gold today. The Wohlwill process creates gold to a high level of purity (99.999 percent).

2021-7-22 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. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process

Wohlwill Process Gold Refining Miller. Wohlwill process Wikipedia. The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). The process was invented in 1874 by Emil Wohlwill. This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold ...

Wohlwill Process Gold Refining Miller . Another largescale gold refining technique, the Wohlwill Process refines gold to 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, 24karat gold as the cathode. wohlwill process procedurewoldes ...

2017-2-7 Hans Emil Wohlwill, a German engineer, invented the Wohlwill Process in 1874. Unlike the Miller Process, which is known among refineries as a relatively cheap and easy way to produce high-purity gold (in the 99.95% purity range), the Wohlwill Process is complex and expensive. But when done correctly, it can produce gold
