Gold Cyanidation Process - 911 Metallurgist

12/08/2015  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. But instead of being floated away from the rock, it is dissolved by the cyanide

What is Gold Cyanidation? (with picture) - InfoBloom

Gold cyanidation extracts gold from the ground. Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
