What is the role of cyanide in mining | MiningFacts.org

Cyanide, in the form of a very dilute sodium cyanide solution, is used to dissolve and separate gold from ore. [3] The process used to extract gold using cyanide was developed in Scotland in 1887, and was first used in large scale commercial mining by the New Zealand Crown Mines Company at Karangahake in 1889.

Gold Cyanidation - Ground Truth Trekking

Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

Clearly the high concentrations of oxygen and cyanide improve initial gold leaching kinetics and thus reduce the residence time and increase throughput; but high cyanide concentrations also increase cyanide consumption. The reported experimental optimum ratio of [CN −]/[O 2] is in the range 4.6–7.4 (Lorenzen and van Deventer, 1992).
