Gold Cyanidation - groundtruthtrekking.org

Process. 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.

Gold Ore Milling Process - freekkusters.nl

Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from mined ore it is then refined to the gold standard purity, according to mineweb heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
