AuCarb™ AC55 Premium Gold Recovery Coconut Shell Activated Carbon

AuCarb™ AC55 Premium Gold Recovery Activated Carbon

High-Performance Coconut Shell Carbon for Gold Mining | 6x12 Mesh Standard

AuCarb™ AC55 is a premium grade of renewable, granular microporous activated Carbon specifically engineered by United Chemical for high-efficiency gold metallurgical recovery operations. Derived from selected high-quality Coconut Shells, AuCarb™ AC55 possesses an optimized sub-nanometer pore structure designed to selectively capture gold-cyanide complexes $[Au(CN)_2]^-$. With an impressive gold adsorption capacity (K-value ≥28 Kg/t) and fast kinetics (R-value ≥55.0%), it serves as an excellent, cost-effective engineering choice for high-volume Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), VAT Leaching, Gold ore heap leaching, and carbon-in-column (CIC) extraction circuits.

Key Features and Process Benefits

• Enhanced Gold Adsorption: Strong K-value and R-value profiles optimize kinetics and ensure maximum loading efficiency during continuous adsorption cycles.
• Excellent Abrasion Resistance: Ball-pan hardness ≥99.0% significantly reduces structural deterioration and carbon fines generation caused by aggressive pulp agitation.
• Low Platelet Content: Strict manufacturing controls maintain a low platelet level (≤5.0%), mitigating screen pegging and maintaining smooth slurry fluidics.
 • Consistent Pore Structure: Minimizes soluble gold losses in tailing slurries while preserving outstanding thermal and chemical reactivation properties across multiple elution loops.

Typical CIP/CIL Design Parameters Reference

For standard industrial metallurgical loops, AuCarb™ AC55 is tailored to support a standard CIP circuit configuration treating 125,000 tonnes of ore per month with a gold head grade of 4g/t (Slurry flow rate: 240 m³/h). Operating seamlessly across 6 consecutive contactors (160 m³ each), it stabilizes a mass of 5 tonnes of carbon per contactor at a transfer rate of 2.75 tonnes per day. For large-scale CIL systems, it easily scales to manage robust circuits with a high throughput of 250,000 tonnes per month (Pulp flow rate: 475 m³/h), ensuring optimized elution metrics.

Standard Packaging, Shipping & Global Logistics

AuCarb™ AC55 is securely packed in standard heavy-duty 25kg (55lb) moisture-proof multi-layer woven bags, or custom UV-stabilized bulk jumbo supersacks (500kg/1000kg) engineered for mine-site environmental resistance. United Chemical handles full maritime containerized logistics compliance, providing streamlined export processing under FOB, CIF, or CFR terms directly to key global gold mining regions across Africa, Central Asia, and South America.
