Summary of Mercury Amalgamation Gold Extraction Process 1. Mercury Amalgamation Gold Extraction Process Principle. The principle of gold extraction by using mercury amalgamation method is mainly that after the mercury is added to the slurry the surface of the gold particles is wetted by mercury and then the mercury diffuses into the interior of the gold particles causing a chemical reaction
