Get PriceJul 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.
[PDF]Get PriceThe widespread use of cyanide among the small-scale gold miners in this study with minimal personal protection is very alarming. This has occurred in Guyana in 1995, Kyrgyzstan in 1998, and Romania in 2000. 8. The small-scale gold miners in this study are a young population of workers.
Get PriceLeaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
