Chemical Reaction Related in the Use of Cyanide in Gold

Cyanide in Gold Mining Sodium cyanide is very toxic and an important chemical as it is used to separate the gold and silver particles from the ore. This process was developed in 1887 which helped make mining for gold easier and safer than extracting gold from liquid mercury. Many production companies make a profit of sodium cyanide as it is more expensive and harder to access raw materials.
