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
