Carbon and Resin Technologies for Gold Recovery | Mining | SGS

This process is very similar to the CIP process. The main differences lie in the preparation of the slurry and method for removing the gold from the leachate. In a CIL process, the carbon is mixed with the leachate solution, not with pulp. This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP process.

Mineral Processing | McClelland Laboratories Inc Reno (775 ...

Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.

Processing, smelting and refining gold | 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.
