United Chemical’s premium gold recovery coconut shell activated carbon series (specifically the high-volume economic grade AuCarb™ BC1100) is engineered specifically for global gold metallurgical extraction operations. Optimized for budget-conscious assets and low-grade ores, it delivers excellent attrition resistance and stable fluidics to maximize output efficiency in large-scale leaching circuits.
AuCarb™ BC1100 Gold Recovery Activated Carbon
High-Volume Standard Carbon for Gold Mining | 6x12 Mesh Special Grade
AuCarb™ BC1100 is United Chemical’s high-volume standard grade of renewable granular microporous activated Carbon, developed specifically to meet the economic and technical demands of modern gold mining operations. Derived from selected premium coconut hulls, BC1100 is heavily optimized for processing low-grade gold ores and budget-sensitive operations. It offers a balanced sub-nanometer pore architecture tailored to selectively extract gold-cyanide complexes [Au(CN)₂]⁻. Highly recommended for mass-scale Gold Ore Carbon-in-pulp (CIP), carbon-in-leach (CIL), VAT Leaching, Heap leaching, and carbon-in-column (CIC) circuits, BC1100 provides a highly competitive, factory-direct commercial alternative to maximize plant capacity without inflating your structural OPEX.
Key Features and Process Benefits
• Tailored for Heap Leaching: Perfect adsorption profile for low-concentration solutions, ensuring stable gold recovery curves in large heap and dump leaching assets.
• Low Attrition & Degradation: Maintains an exceptional ball-pan hardness (≥99.0%), successfully minimizing structural carbon collapse and grain wear during continuous circuit circulation.Low wear can extend product lifespan,.
• Minimal Platelet Content: Strict production screening guarantees exceptionally low platelet rates (≤5.0%), actively preventing screen pegging, inter-tank clogging, and operational downtime.Low Platelet Content reduces gold loss.
• High Cost-Efficiency: Provides reliable gold loading metrics combined with an aggressive bulk commercial pricing model, making it the ideal choice for high-volume inventory replenishment.
AuCarb™ BC1100 Premium Gold Recovery Activated Carbon
The Ultimate 6x12 Mesh Carbon for Heap Leaching & CIC Circuits
AuCarb™ BC1100 is United Chemical’s flagship coarse-granular (6x12 Mesh) microporous Activated Carbon, engineered explicitly for high-efficiency gold recovery in Heap Leaching, Vat Leaching, and Carbon-in-Column (CIC) operations. Formulated from selectively sourced premium mature Coconut Shells and activated via advanced high-temperature steam processes, BC1100 is designed to process hard ores under the most rigorous mining conditions.
By prioritizing exceptional ball-pan hardness (tested at 99.3%) and a massively developed microporous matrix (Iodine number ≥1100 mg/g), BC1100 guarantees superior wear resistance, minimal head pressure drop, and the absolute lowest rate of soluble gold loss through carbon attrition.
Why Choose AuCarb™ BC1100?
| Core Advantage | Metallurgical Impact |
|---|---|
| Extreme Hardness (≥99%) | Drastically minimizes carbon structural collapse, flaking, and attrition under aggressive agitation and harsh fluidization across CIP, CIL, and CIC circuits, effectively preventing precious metal loss into the tailing dams. |
| Optimized 6x12 Mesh Size | Provides the perfect balance between mass transfer kinetics and hydraulic conductivity. Ensures excellent solution flow rates and prevents screen pegging or clogging in heap leach pads. |
| High Iodine Value (≥1100 mg/g) | Indicates a highly developed sub-nanometer pore architecture that is mathematically matched to selectively capture the gold-cyanide complex ion [Au(CN)2]-. |
| Low Attrition & Platelets | Features an extremely low wear rate (2%) and very minimal platelet content (5%), it significantly improves product lifespan and prevents the loss of gold-loaded fine powder in the adsorption and elution loops, thus reducing gold loss. |
