United Chemical — Premium Coconut Shell Activated Carbon for Gold Recovery

Short product intro 
United Chemical’s Premium Coconut Shell Activated Carbon is engineered for maximum gold recovery performance in CIP, CIL, CIC and heap-leach systems. Made from select Southeast Asian coconut shells and processed through precision carbonization, high-temperature activation and proprietary particle-shaping, the product combines exceptional adsorption activity with industry-leading mechanical durability — COA-verified for reliability in demanding mining environments.

Key Benefits — What makes our carbon better

• COA-verified performance — lab results (sample dated Nov 29, 2025) confirm K-Value ≥ 26 kg/t (≈26 g Au/kg), R-Value ≥ 50%, CTC ≥ 50%, Butane Activity ≥ 19.5%.

• Ultra-high mechanical strength — engineered particle shape and high hardness (premium model) reduce fines and attrition, lowering carbon losses and makeup costs.

• Optimized pore architecture — well-developed micropores and large surface area deliver fast adsorption kinetics and high equilibrium loading of Au(CN)₂⁻.

• Ready-to-use, low-maintenance — particles are pre-shaped to remove weak, needle or angular fragments; minimal preprocessing (water wash) required.

• Excellent elution and regeneration — efficient desorption enables multiple reuse cycles, reducing total cost of ownership.

• Stable batch quality & traceability — consistent specs, full COA and batch traceability available upon request.

Performance Metrics — what these mean for your plant

• Higher K and R values = more gold adsorbed per unit of carbon and faster kinetics — directly increases gold recovery and throughput.

• Low attrition & high hardness = fewer fines, less screening and electrowinning contamination, reduced makeup carbon and lower OPEX.

• Optimized particle distribution (6×12) = stable bed porosity, less screen plugging and predictable hydraulic behavior.

• Excellent elution response = efficient gold strip and reliable regeneration cycles, improving carbon life and cash flow.

Typical Applications

• Carbon in Pulp (CIP) circuits

• Carbon in Leach (CIL) plants

• Carbon in Column (CIC) adsorption systems

• Heap leaching adsorption with carbon capture

• Elution and regeneration circuits feeding electrowinning

• Secondary uses: industrial adsorption, water treatment (grade-dependent)

Handling & Use Recommendations (quick guide)

1. Pre-use: Rinse with water to remove transport dust; no grinding required for premium particle shapes.

2. Loading: Follow your plant’s standard inventory and dosing practice; monitor carbon fines and screen performance.

3. Elution: Standard elution temperatures and eluents apply; check COA for specific ash/pH interactions.

4. Regeneration: Multiple cycles expected — monitor K and R over life cycles to plan makeup.

5. Safety: Store in dry, ventilated area; follow local regulations for handling and transport of activated carbon.
