900 Iodine Value Coconut Shell Carbon for Gold Recovery

Huajing’s 900 Iodine Value Coconut Shell Carbon for Gold Recovery centers its core advantages on three key dimensions: high adsorption capacity, high abrasion resistance, and high purity. With a stable iodine value meeting the standard of 900 mg/g and an ample specific surface area, it demonstrates high adsorption efficiency for gold-cyanide complexes and possesses a large gold-loading capacity, thereby effectively reducing carbon loss and gold recovery costs. The product boasts a mechanical strength of ≥98%; it resists pulverization during the Carbon-in-Pulp (CIP) and Heap Leaching production processes, thereby mitigating the risks of pipeline blockages and gold loss.
Furthermore, its low ash content and minimal impurities ensure that no additional contaminants are introduced, thereby safeguarding the purity of the refined gold.
This product is primarily utilized in scenarios such as heap leaching gold recovery at mines, CIP gold extraction, desorption and electrolysis of gold-loaded carbon, precious metal recovery from electronic waste, and gold slime enrichment and purification. It is compatible with various large, medium, and small-scale gold smelting production lines, and its long-term application can significantly enhance overall gold recovery yields.

Technical Parameters

Production Details and Quality Comparison

From raw material selection to final product shipment, Huajing’s 900 Iodine Value Coconut Shell Carbon for Gold Recovery undergoes a rigorous quality control process spanning 12 distinct stages. Raw materials are carefully selected—specifically high-quality, mature coconut shells characterized by dense fibers and superior inherent strength. Carbonization temperatures are precisely controlled, and activation times are sufficiently extended to ensure the development of a robust internal microporous structure with uniform distribution. The production process involves no chemical additives, thereby preventing impurities from compromising the efficacy of gold adsorption.
Compared to ordinary low-iodine-value coconut shell carbons available on the market, this product offers a 15%–25% increase in gold adsorption capacity, boasts an abrasion resistance that is over 10% higher, offers a longer service life, and exhibits a significantly lower pulverization rate. The factory is equipped with a professional laboratory where every production batch undergoes rigorous testing for key parameters—including iodine adsorption value, mechanical strength, moisture content, particle size distribution, and ash content. Each shipment is accompanied by an original factory Quality Inspection Report, ensuring that the delivered products precisely match the approved samples and effectively eliminating any possibility of substituting inferior goods for high-quality ones.

Usage Instructions and Precautions

The 900 Iodine Value Coconut Shell Carbon for gold recovery does not require excessive washing prior to use; over-washing may damage the porous structure and compromise adsorption efficiency.
Select the appropriate particle size based on your specific gold recovery process: fine-grained carbon is recommended for the Carbon-in-Pulp (CIP) method, while medium-to-coarse-grained carbon is recommended for heap leaching processes.
Handle the carbon gently during loading to minimize mechanical breakage; regularly inspect for any accumulation of carbon fines to prevent obstruction of fluid flow.
Store the product in a dry, well-ventilated environment, away from acidic or alkaline chemicals, to prevent moisture absorption and contamination that could degrade performance.
