  • Summary of Mercury Amalgamation Gold Extraction Process Summary of Mercury Amalgamation Gold Extraction Process

    Jan 04, 2020 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. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form. When the obtained solid matter is heated, the mercury
