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 percent purity. The Wohlwill process .
At this point in the process, direct smelting can often be employed as the final stage of gold recovery. In direct smelting highgrade concentrate is heated until the gold melts. The liquid is then cooled to form a solid mass of gold dore, a semi pure gold alloy, that can reach upwards of 95% purity.
Metallurgical ContentLearn CyanidationDevelopments in the CarbonInPulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a ...
(0 – 50%). Therefore, gravity recovery is usually followed by additional gold recovery operations such as cyanidation and/or flotation. The amenability of a gold orebody to gravity treatment is dependent on the size and liberation characteristics of the individual gold particles in the ore. Relatively coarse gold .
