Gold Smelting Refining Process

Feb 28, 2016  Intensive cyanidation is a good option, but obviously, the material can be sent to the leaching process employed to treat the raw ore. Gold and silver recoveries are between 99.5 to 99.7%. Although slag production weight is variable, a typical operation can generate 10 kilos of slag per 1000 oz of 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 ...
