    Rock Gold Processing It usually uses the process of Gravity Separation, Flotation, Amalgamation, Cyanidation, RIP (resininpulp process), CIL/CIP, and heap leaching to extract gold In the practical production, the processing of gold is jointly adopted rather than limited to one single process method Here’re some common methods: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 produces gold of only about 995 percent purity TheGold Refining | From Gold Ore to Doré | World Gold Council· Refining Gold by by Oxidation Using Air to Refine Gold by Oxidizing The use of a blast of air on the surface of molten gold or silver is probably the oldest of the refining processes The method appears to be described in the Book of Ezekiel, to which the date BC 593 is assigned, and the principle is the same as in cupellation, which wasGold Refining Methods Mineral Processing & Metallurgy
