Mercury Usage in Gold Mining and Why It Is a Problem

2019-7-22 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.
