Carbon Adsorption In Recovery Of Gold - Mine Engineer.Com

The carbon in pulp method is only used where tank leaching is utilized for the recovery of gold from the ores and this is not the case in most large gold mines today, since heap leaching is the lowest cost method for recovering gold from ores containing from a few grams to 5 or 6 grams per ton.

Gold Recovery Jacobi Carbons

Carbon-In-Leach. Carbon-in-leach combines leaching with the carbon-in-pulp process, creating a single unit process operation. Usually this method is chosen when native carbon (a high organics load) is present in the gold ore, adsorbing the leached gold and preventing its recovery.

Estimating process design gold extraction, leach residence ...

May 01, 2015  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.

Gold ore Carbon-In-Leaching (CIL) processing technology ...

The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. 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).

3. Carbon-In-Leach (CIL): The carbon-in-leach process integrates leaching and carbon-in-pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

Heap Mining Efficiently Leaches Lower Grade Gold from S

The ADR plant uses a series of tanks loaded with carbon particles to extract the gold from the cyanide solution. Gold loves carbon even more than cyanide. After leaving the ADR plant and “loading the carbon”, the solution is recycled to the heap to recover any gold precipitated in the leach solution and to reduce cyanide costs.
