Gold Cyanidation

Gold Cyanidation

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.

Cyanide Use in Gold Mining

Cyanide Use in Gold Mining

Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks. Although the chances of spills are lower because the leaching process is more controlled, the resulting waste, known as tailings, is stored behind large dams (tailings impoundments) which can and do fail astrophically. Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it ...
