Gold ore Carbon-In-Leaching (CIL) processing

The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto cathodes of steel wool. The

How to Process Gold Ores by Heap Leaching

During startup of a countercurrent carbon adsorption system for processing heap-leach cyanide effluents, the first or lead column of carbon may adsorb all of the precious metal values. After the carbon has been in service for some time and carries about 20 ounces of gold per ton, a gradual break-through of gold will occur in the effluent from the first column and he adsorbed by the succeeding bed of carbon.

The Metallurgy of Cyanide Gold Leaching – An

The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution resulting in very high loadings on the carbon (typically 1000-4000 g/t). At the end of the leach the loaded carbon is removed from the slurry and the adsorbed gold is stripped out at high temperature and pressure with sodium hydroxide and cyanide solutions to form a high value electrolyte solution.

Activated carbon also consumes cyanide, so its effect has to be accounted for in the case of carbon-in-leach (CIL) or carbon-in-pulp (CIP) plant flowsheets. Since cyanide is an expensive reagent, often a major component of plant operating costs, it is important that the scale-up of cyanide consumption from laboratory to plant be representative.
