Cyanide control in the metallurgical process of gold

AngloGold South Africa region currently consists of twelve gold plants. These plants use a combined total of $20 million of cyanide per annum. Of this, the major portion (60%) is consumed at two Ergo dump retreatment plants. Historically the primary motivation for cyanide control at Ergo has been one of leach/cost optimization.

Highlights 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
