Jul 22 32 A mercury gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury leaving behind the gold This process does not result in gold that is 100 pure but it does eliminate the bulk of the impuritiBromine acts more energetically than chlorine and has also been employed in the extraction The recovery of the gold is effected similarly and the bromine is then liberated by the action of chlorine but it is impossible to prevent loss of bromine Cyanide process The extraction of gold by the cyanide method is of great technical importance

Fine Gold Recovery Equipment and Black Sand Clean Up Tools This recovery equipment is specifically designed to reduce the amount of raw gold bearing material to a manageable amount for further processing and/or aid directly in the separation of finer grains of gold During the CIL process gold is leached from the ore using an alkaline cyanide solution The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon Elution is the next step in the process whereby the adsorption of the gold cyanide complex onto carbon is reversed
