  • Activated Carbon for Gold Recovery | Puragen Activated

    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 carbon-in-column (CIC) operating systems.
