How Cyanide Leaching Is Used In Gold Mining

jul 03, 2015 cyanide is used to extract gold from ore where it is spread throughout the ore in fine amounts. It is also usually done in conjunction with a process such as grinding, milling or a gravity separation that increases the surface area of the ore to expose as much gold as possible; this is done because the sodium cyanide solution has no effect on
