Improving the process performance of gold cyanide leaching

In the gold mining industry today cyanide leaching is the prevailing method for solubilizing and recovering gold. Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon Fleming et al. 2011 . Typically the carbon in pulp CIP or carbon in leach CIL process is used for gold recovery. These

ACT - Granular Activated Carbon for Gold Recovery

Highly activated carbon is used in the dissolved gold recovery process either by introducing it directly into the CIL carbon-in-leach tanks or into separate CIP carbon-in-pulp tanks after leaching. The activated carbon adsorbs the dissolved gold from the leach slurry thereby concentrating it onto a smaller mass of solids.

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
