Gold Refining | From Gold Ore to Doré | 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.miller and wohlwill processes of gold refining,Miller Process Gold Refininglh-nehtiky .

A variant of the Wohlwill process is the fizzer cell.
