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.
