Effect of activated carbon on the thiosulfate leaching of gold

The use of activated carbon as catalyst in the thiosulfate leach of gold is a process alternative that may not require the addition of surrogate oxidants (like copper), can work at temperatures as low as 30 °C, and thiosulfate degradations of 21 kg per ton of ore or lower, making it an attractive alternative for the leaching of gold.

Gold Mining Process Development

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.

Leaching & Adsorption Resource Book

Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry The method of recovery of gold from the process slurry is by carbon adsorption Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

Gold Extraction and Recovery Processes

The common processes for recovery of gold solution includes: (i) Carbon adsorption, Merrill-Crowe process, (iii) electrowinning and (iv) ion-exchange / solvent extraction Traditionally, Merrill-Crowe process was used to remove gold from a cyanide solution by using zinc dust to precipitate gold.
