Cyanide Use in Gold Mining - Earthworks

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 catastrophically. Cyanide's efficiency makes mining more wasteful
