Coconut Shell Activated Carbon for Gold Extraction

Coconut shell activated carbon for gold extraction is a specially engineered granular adsorbent, exclusively produced from high-quality coconut shells through precise carbonization, high-temperature steam activation, acid pickling, classification and surface modification. It is widely applied in gold hydrometallurgy processes including Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL) and heap leaching, serving as the core material for adsorbing and recovering gold cyanide complexes from alkaline cyanide solutions.

Featuring a high specific surface area (1000–1500 m²/g), well-developed microporous structure and high mechanical strength, it exhibits strong adsorption capacity and high selectivity for gold, effectively reducing gold content in tailings to an extremely low level. With outstanding abrasion resistance and chemical stability, it resists pulverization under stirring and pumping, and remains stable in alkaline cyanide systems. The loaded carbon can be easily desorbed, electrolyzed and regenerated for recycling, which significantly lowers production costs and improves gold recovery efficiency.

It is characterized by fast adsorption rate, high gold loading, low loss rate and long service life, making it an indispensable key material in modern industrial gold production.
