Mercury Usage in Gold Mining and Why It Is a Problem
Jul 22, 2019· 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. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.
