The Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated.

Gold cyanidation in field scale is mainly conducted through heap leaching and tank leaching methods. The choice between alternatives depend on several factors including grade of precious metals in the ore, size of the reserve, etc. Regardless of the method selection, the liability of the Au bearing ore to cyanidation is the most critical aspect.

cyanidation process, granular activated carbon is added to the leached slurry. The carbon adsorbs the gold from the slurry solution and is removed from the slurry by coarse screening. In practice, this is accomplished by a series of five or six agitated tanks where carbon and ore slurry are contacted in a staged countercurrent manner.
