Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated sub-optimally. Optimum design criteria and operating conditions are easily determined with simple test work and

Elution and Carbon Reactivation - Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
