Mercury Usage in Gold Mining and Why It Is a Problem

Mercury Usage in Gold Mining and Why It Is a Problem

Jun 25, 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 100 percent pure, but it does eliminate the bulk of the impurities.
