Gold Cyanidation -

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. This process usually takes place inside a mill or other mining facility
