The final stage of gold production refining involves removing impurities that remain after the smelting companies receive doré 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.
Amalgamation is a concentrating process in which metallic gold or silver, or an alloy of the two, is mixed with mercury, either in a amalgamation drum, or on a amalgamation table, where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste (barren) ore pulp are caused to travel different paths to effect ...
