What Are the Methods for Gold Processing?

This gold processing method is suitable for gold-bearing quartz veins with misproportion dissemination and low-sulfur. Since the monomer-separated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This gold extraction process is a widely used process in China's gold processing plant, in which the gold

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. The Miller process is rapid and simple, but it produces gold of only
