Processing smelting and refining gold

***copper remains in gold 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
