AuCarb™ AC60 Premium Gold Recovery Activated Carbon Coconut Shell Carbon for CIP/CIL/CIC Gold Mining

High-Kinetics Coconut Shell Carbon for Gold Mining | 6x12 Mesh & 8x16 Mesh

United Chemical’s newly developed premium gold recovery coconut shell activated carbon series (specifically the flagship grade AuCarb™ AC60) is engineered specifically for global gold metallurgical extraction operations. Featuring an ultra-dense microporous matrix and exceptional mechanical rigidity, it guarantees the lowest rate of soluble gold loss in tailing slurries.

AuCarb™ AC60 is United Chemical’s flagship grade of renewable, granular microporous activated Carbon, engineered explicitly for high-efficiency gold metallurgical recovery processes. Formulated from premium-grade coconut hulls, AuCarb™ AC60 features an extensively developed sub-nanometer pore size distribution optimized to selectively capture gold-cyanide complexes [Au(CN)₂]⁻. It delivers outstanding gold loading kinetics (R-value ≥60%) and high adsorption capacities (K-value ≥30Kg/t), making it highly recommended for initial filling and carbon replenishment in demanding Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), VAT Leaching, Gold ore heap leaching, and carbon-in-column (CIC) loops.

Key Features and Process Benefits

• Rapid Adsorption Kinetics: Exceptional R-value ensures accelerated gold extraction rates, even in heavily fouled or high-viscosity circuits.
• Extreme Resistance to Attrition: Ball-pan hardness ≥99.0% minimizes carbon structural collapse and degradation under aggressive reactor agitation and inter-particle friction.
• Negligible Carbon Fines Loss: Highly rigid profile prevents screen pegging, clogging, and subsequent precious metal loss into the tailing dams.
• Excellent Regeneration Performance: Maintains excellent 3-dimensional shape, structural pore integrity, and low head losses across multiple thermal reactivation and acid-washing cycles.

AuCarb™ AC60 Premium Gold Recovery Activated Carbon

High-Kinetics Coconut Shell Carbon for Advanced Gold Mining | 6x12 Mesh & 8x16 Mesh

AuCarb™ AC60 is United Chemical's flagship grade of renewable, granular microporous Activated Carbon, engineered explicitly for high-efficiency gold metallurgical extraction operations. Formulated from carefully selected, ultra-hard, mature coconut husks, it undergoes a proprietary high-temperature steam activation process to develop an ultra-dense, highly specific sub-nanometer microporous matrix.

This unique pore architecture is mathematically matched to the molecular size of the gold-cyanide complex ion, [Au(CN)₂]⁻. By prioritizing kinetic adsorption speed (R-value) and maximum gold loading capacity (K-value), AuCarb™ AC60 guarantees the lowest possible rate of soluble gold loss in tailing slurries. It is the definitive carbon choice for initial filling and ongoing carbon replenishment in high-demand Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), Carbon-in-Column (CIC), and Vat/Heap Leaching loops.

Core Features & Metallurgical Process Benefits

• Rapid Adsorption Kinetics (R-Value ≥ 60.0%): Time is money in metallurgical circuits. The exceptional R-value ensures accelerated gold extraction rates from the pregnant leach solution (PLS). This allows for shorter retention times in the contactors, maintaining high efficiency even in heavily fouled, organic-rich, or high-viscosity ore slurries to prevent "preg-robbing" effects.

• Massive Gold Loading Capacities (K-Value ≥ 30 Kg/t): Driven by an optimized Carbon Tetrachloride (CTC) activity rather than generic surface area, AC60 selectively targets precious metals. This high equilibrium loading capacity maximizes the ounces of gold recovered per metric ton of carbon, significantly reducing the frequency of elution cycles and lowering operational stripping costs.

• Extreme Resistance to Attrition (Ball-Pan Hardness ≥ 99.0%): In rigorous CIP/CIL mixing tanks, carbon is subjected to aggressive mechanical agitation and inter-particle friction. AC60 boasts a dense structural integrity that drastically minimizes carbon breakdown, flaking, and structural collapse.

• Negligible Carbon Fines Generation: The greatest hidden cost in gold mining is precious metal lost to the tailing dams via microscopic carbon dust. By maintaining a strict attrition loss rate of ≤ 2% (AARL Method), AuCarb™ AC60 prevents screen pegging, interstage screen clogging, and subsequent soluble gold loss.

• Superior Thermal & Chemical Regeneration: A premium carbon must perform consistently over its lifespan. AC60 maintains an excellent 3-dimensional shape, structural pore integrity, and low head losses across multiple acid-washing (to remove calcium/magnesium scaling) and thermal reactivation kiln cycles, ensuring a high return on consumable investment.
