Gold Cyanidation Process - Mineral Processing & Metallurgy

 · 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.
