Processing, smelting and refining gold World Gold Council 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.Get Price

Wohlwill process Wikipedia The Wohlwill process is an industrial-scale stone 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 to serve as an anode.Lower percentages of gold in the anode will interfere with the reaction, especially when theGet Price
