Factors influencing the rate of gold cyanide leaching and

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 Get price
