    Gold Refining From Gold Ore to Dor233; 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. The Miller process is rapid and simple but it .
