AuCarb™ AC60 Premium Gold Recovery Coconut Shell Activated Carbon

AuCarb™ AC60 Premium Gold Recovery Activated Carbon

High-Kinetics Coconut Shell Carbon for 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 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 230Kg/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.
• High Gold Loading Capacities: Iodine number ≥1200 mg/g guarantees maximum carbon loading, significantly reducing soluble gold losses in tailing management.
• 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.

Typical CIP/CIL Design Parameters Reference

For a standard CIP circuit with a treatment capacity of 125,000 tonnes per month and a gold head grade of 4g/t (Pulp flow rate: 240 m³/h), AuCarb™ AC60 is highly optimized for configurations of 6 contactors (Volume: 160 m³ per contactor). It maintains a steady-state mass of 5 tonnes of carbon per contactor with a recommended carbon transfer rate of 2.75 tonnes per day, ensuring smooth elution operations and minimized refinery inventories. For high-capacity operations, it easily scales to CIL setups treating 250,000 tonnes per month efficiently.

Standard Packaging, Shipping & Global Logistics

AuCarb™ AC60 is packed in heavy-duty 25kg (55lb) dual-layer moisture-proof woven bags, or UV-stabilized bulk jumbo bags (500kg/1000kg) tailored for rugged mine-site storage. United Chemical provides complete global maritime export compliance documentation, guaranteeing smooth customs clearance and secure containerized shipping via FOB, CIF, or CFR terms to major global mining sectors across Africa, Central Asia, and South America.
