Thus it is sensible to know accurately, at all times, feed grade to the processing facility and how much oxygenated cyanide recoverable gold is available from a given plant under optimum operating conditions. Equally as importantly anything that can clearly indicate whether plant leach conditions are in fact optimum, is useful.

Gold Carbon In Leach Plants Updated January 2017. Gold Processing Plant, Carbon In Leach (CIL) Plant. ... Cyanide is added, typically in the first tank. Each carbon leach tank has a interstage screen in it for carbon retention. Slurry can gravity flow between tanks or be pumped. Typically there are 4 .

Slurry then goes to the tailings processing facility and the carbon is delivered to the elution circuit where gold is recovered using electrowinning process. Tailings produced from the plant are treated using a combination of tailings washing and thickening and an air/sulphur dioxide (air/SO 2) cyanide detoxification system before disposal.
