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.
The use of low-cost cyanide heap leaching techniques to recover metal from ores has allowed miners to profitably extract gold deposits. The chemical compound has on occasion been mishandled, and in some loions releases have created environmental problems. However, worldwide, the mining industry has shown it can work with cyanide responsibly.
