The ISA mill was commissioned in October 2005 and provides additional incremental liberation of the fine refractory gold (2-5 microns) enclosed in pyrite. The flotation tailings with an average grade of 0.45 gram of gold per tonne are thickened to 50% solids and subjected to cyanidation for ten hours in a CIL circuit similar to the circuit used ...
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.
