Gold Extraction and Precious Metal Recovery: Coconut Shell Activated Carbon in Hydrometallurgy

Low gold loading capacity, high attrition rate and poor desorption efficiency are common technical challenges in gold mine CIP (Carbon-in-Pulp) and CIL (Carbon-in-Leach) processes. Coconut shell activated carbon, with its unique natural pore structure and excellent mechanical strength, can efficiently adsorb gold cyanide ions, achieving stable gold extraction and precious metal recovery from various ore types and leaching solutions.

Coconut shell activated carbon has excellent adaptability in hydrometallurgical applications. It can be directly filled into CIP/CIL agitation tanks, heap leaching adsorption columns and desorption equipment for continuous gold extraction, or applied to precious metal recovery from electronic waste and electroplating effluents. In production systems, coconut shell activated carbon not only selectively adsorbs precious metals such as gold, silver, platinum and palladium, but also maintains good fluidity, reduces agitation wear and ensures long-term stable operation of equipment. When matched with desorption-electrolysis units, it achieves efficient gold desorption and activated carbon regeneration, effectively reducing production costs.

Selecting high-quality coconut shell gold activated carbon requires attention to three core indicators: gold loading capacity, abrasion resistance and iodine value. High gold loading capacity reflects the activated carbon's adsorption ability for gold, directly determining the gold recovery rate. High abrasion resistance guarantees compression and wear resistance, not easy to break or produce fine powder during long-term circulation, reducing carbon loss and gold loss. Furthermore, reasonable particle size specifications (6x12 mesh / 8x16 mesh / 12x20 mesh) ensure good hydrodynamic performance, avoid channeling and short-circuiting, and improve overall process efficiency.
