In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery

Extraction of Gold

Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanide-process The extraction of gold by the cyanide-method is of great technical importance.

Activated carbon reduces fines formation and increases yield. A major use of activated carbon in mining is in gold recovery, where granular activated carbon (GAC) is used for adsorption of the gold-cyanide complex in carbon-in-pulp (CIP) and carbon-in-leach (CIL) systems, or in carbon-in-column (CIC) systems after a heap leach operation carbon.

Gold extraction QueensMineDesignWiki

2019-6-28  The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered.
