Gold Mining By Amalgamation Process

Gold Amalgamation Process Principles The amalgamation process which has been widely used in a variety of forms from earliest times depends upon the wetting and alloying of metallic gold and silver with mercury Because of its high specific gravity and tendency to be collected by larger masses of liquid mercury or mercurycoated surfaces this alloy or amalgam is readily separated from the lighter
