United Chemical — Premium Coconut Shell Activated Carbon for Gold Recovery

United Chemical’s flagship 2026 coconut shell activated carbon is engineered for maximum gold recovery performance in CIP, CIL, CIC and heap leaching systems. Sourced from high-grade Southeast Asian coconut shells and produced with precision carbonization, high-temperature activation and an advanced particle-shaping process, this product pairs industry-leading adsorption activity with exceptional mechanical durability — fully verified by our latest COA (sample date: Nov 29, 2025).

Key Selling Points — Why United Chemical Carbon Wins

• Proven COA Performance (real lab data):
  K-Value (gold adsorption capacity) ≥ 26 kg Au / t C
  R-Value (adsorption rate) ≥ 50%
  CTC Activity ≥ 50%
  Butane Activity ≥ 19.5%

  These metrics translate to faster gold capture, higher equilibrium loading and lower residual gold in barren solutions.

• Unmatched Mechanical Strength:
  Ball-Pan Hardness ≥ 99% and Attrition Loss ≤ 1.5% minimize carbon fines and mechanical losses during circulation. Less carbon breakage means fewer losses to tailings, less screening maintenance and lower make-up consumption.

• Tight Particle Control for Reliable Operation:
  Standard 6×12 mesh meeting ASTM D2862 particle distribution ensures smooth screening, stable bed porosity and predictable hydraulic performance in adsorption tanks and columns.

• Low Impurities, High Stability:
  Ash ≤ 4% and Moisture ≤ 5% support consistent adsorption behavior and reduce impurities that can interfere with elution and electrowinning.

• Optimized Adsorption Structure:
  Advanced activation yields a highly developed micropore network and large surface area for superior Au(CN)₂⁻ capture and fast kinetics, enabling shorter residence times and higher throughput.

• Easy Desorption and Regeneration:
  Excellent elution response supports efficient gold recovery from carbon and multiple regeneration cycles, lowering total cost of ownership across the life of the plant.

• Designed for High-Density and Multi-Cycle Systems:
  Performance remains stable under high pulp density and repeated adsorption–elution cycles, making it ideal for modern, high-capacity operations.

Operational Benefits — Real Value for Mining Projects

1. Higher Recoveries, Lower Losses
   Superior adsorption capacity and kinetics reduce gold in tailings and improve plant gold yield.

2. Lower OPEX from Reduced Carbon Makeup
   Low attrition and long cycle life reduce replacement frequency and logistic cost.

3. Less Downtime and Maintenance
   Uniform particle size and low fines lower screening and pump blockages — fewer interruptions, more uptime.

4. Faster Ramp and Predictable Scaling
   High R-Value shortens adsorption residence time, enabling higher throughput without hardware changes.

5. Easier QA/QC and Supply Reliability
   Consistent batch performance and available COAs simplify plant qualification and procurement decisions.
