Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019 How Mercury Is Used in Gold Mining. First, mercury is mixed with the materials containing gold. 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.

Silver and mercury in gold particles from the Proterozoic

Gold particles in systematically collected ore samples from the Proterozoic Carbon Leader Reef paleoplacer were studied by ore microscopy and analyzed for their silver and mercury contents.
