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.
The cyanide leaches the gold out, but the cyanide can seep into the ground, causing environmental problems and posing threats to human health. Researchers at Northwestern University recently
