Mercury Usage in Gold Mining and Why It Is a Problem

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 pure but it does eliminate the bulk of the impurities.
