The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process Refining companies receive dor bars as well as scrap gold and reliquefy the metal in a furnace Workers add borax and soda ash to the molten metal which separates the pure gold from other precious and less precious metals A sample is then taken to a lab for tests or

Cyanide Leaching Of Gold

Once the gold has been dissolved in the cyanide and the ore body has been reasonably depleted of its gold there are two main processes for recovering the gold from the pregnant cyanide solution One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold

Sep 29 2011Cyanide is the complexing agent that helps to remove plated deposits into solution Nitro-aromatic compounds are the source of the oxidizing power The use of cyanide-containing stripping agents began declining in the 1970s as industry moved towards safer process chemicals
