Gold mining - Wikipedia

Cyanide process Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solutionHow Is Gold Extracted From Gold Ore? | Sciencing,The zinc causes a chemical reaction which separates the gold from the ore The gold is then removed from the solution with a filter press For the carbon-in-pulp method, the ground ore is mixed with water before cyanide is added Then carbon is added to bond with the goldGold Mining and Processing: Everything you Need to Know,The once primitive, cumbersome mining methods used during that time has developed into compact, efficient modern-day equipment that makes gold mining a more cost-effective, efficient process Likewise, the mining equipment used today helps reduce waste and chemical exposure throughout the various phases of gold mining
