Gold Recovery with Activated Carbon
High-performance coconut-shell granular carbon for CIP and CIL circuits — engineered for gold loading, elution efficiency and long service life in aggressive mining duty.
Carbon That Keeps Its Teeth
In carbon-in-pulp and carbon-in-leach plants, carbon is screened, pumped and stripped continuously. Only coconut-shell GAC combines the micro-porosity needed for gold loading with the hardness needed to survive abrasion and multiple regeneration cycles.
- ✓Hardness ≥98% for low attrition losses
- ✓High activity for fast gold loading
- ✓Tight particle sizing for clean screening
- ✓Stable supply for plant-scale volumes
The Three Properties That Matter
Hardness & Abrasion
High mechanical strength minimizes fines and carbon losses during pumping, screening and regeneration.
Micro-Porosity
A narrow micro-pore distribution maximizes gold loading capacity and elution efficiency.
Low Ash & Purity
Low ash content reduces interference in stripping and kiln regeneration, protecting plant economics.

Which Activated Carbon for Gold Recovery? — 3-Way Comparison
For CIP/CIL gold recovery, the carbon type decides how much gold you keep. Compare hardness, pore structure and suitability below.
| Carbon Type | Hardness | Pore Structure | Suitability for Gold (CIP/CIL) |
|---|---|---|---|
| ✔ Coconut Shell Carbon — BEST | ≥ 98% (extreme) | Micropores | ✔ Hard coconut-shell GAC for CIP/CIL circuits — selected for high hardness, low fines generation and good gold-loading capacity under suitable operating conditions |
| ⚠ Coal-Based Carbon | 80–90% (soft) | Mesopores | ⚠ Usually less suitable where maximum hardness and low fines are critical; selection depends on ore, circuit and attrition conditions |
| ✖ Wood-Based Carbon | < 70% (very soft, dusty) | Macropores | ✖ Usually not selected for CIP/CIL where mechanical strength and low fines are critical |
Common Questions About Gold-Recovery Carbon
Which activated carbon should I use for gold recovery?
Coconut shell activated carbon (6×12 mesh, hardness ≥98%, iodine 1000–1300 mg/g) is the recommended grade for CIP/CIL gold recovery — it resists breakdown in agitation tanks and captures the gold-cyanide complex efficiently.
Why does carbon hardness matter in a CIL or CIP plant?
Soft carbon breaks into fines in the tanks; carbon fines are screened out and carry adsorbed gold out of the circuit, causing direct gold loss. Coconut shell carbon with ≥98% hardness stays intact.
How much activated carbon will my plant consume?
Consumption depends on plant throughput, ore type and circuit design. Send us your plant size and we will recommend a dosing rate and estimate annual carbon usage.
Can I test your carbon on my ore before ordering?
Yes. The standard 500 g sample is free. International courier charges are paid by the buyer; shipping within mainland China is included. Larger trial lots are quoted separately. The sample is supplied with the COA of its lot.
