extract gold by cyanide mill process

Donlin Gold The Mining Method Extracting Gold

A process called "pressure oxidation" is used to oxidize the goldbearing materials. The oxidized material is mixed with a cyanide solution in large tanks inside the mill. The gold dissolves in the cyanide. The dissolved gold is then collected onto activated carbon, and the cyanide solution is sent to a cyanidedetox unit.
