Thiol functionalized activated carbon for gold thiosulfate recovery,
2023.2.1 Abstract. Cyanide salts are currently used as leaching agents in gold extraction processes despite their toxicity. Thiosulfate is a greener choice, but its employment is constrained by the difficulty at recovering gold thiosulfate from the leachate using activated carbon, which in contrast, works well for gold-cyanide adsorption.

Activated Carbon Gold Recovery - Puragen Activated Carbons
Activated Carbon for Gold Recovery. Activated carbon has long been used as an adsorbent in the gold processing industry to recover gold from mining operations. Due to its high surface area and exceptional hardness, coconut shell GAC (granulated activated carbon) is the main product used in carbon-in-leach (CIL), carbon-in-pulp (CIP), and ...
