CIL circuit makeup carbon6×12 coconut-shell grade evaluated for attrition, activity and screen retention.
Carbon-in-pulp and carbon-in-leach recovery
Hard coconut-shell activated carbon adsorbs dissolved gold-cyanide complexes in CIP, CIL and related recovery circuits. Adsorption activity, particle size, hardness and resistance to attrition directly affect recovery and carbon losses.

Product parameters
Recommended starting ranges for technical discussion. Final values depend on the stream, test method and buyer specification.
| Carbon option | Iodine value | Typical size | Suitable conditions | Selection effect |
|---|---|---|---|---|
| CIP grade coconut GAC | 1000–1200 mg/g | 6×12 mesh | CIP adsorption trains | High hardness and rapid kinetics |
| CIL grade coconut GAC | 1000–1200 mg/g | 6×12 mesh | CIL tanks with carbon transfer | Low platelets and controlled size |
| Fine-mesh recovery carbon | 1000–1200 mg/g | 8×16 mesh | Specialized contact systems | Higher external area |
| Regeneration makeup carbon | Buyer specification | 6×12 mesh | Replacing circuit losses | Consistent activity and strength |

Frequently asked questions
Need a faster review? Send the available process data with your inquiry.
Yes. Share your process data and target limits so we can prepare a relevant evaluation sample. Freight is normally paid by the buyer.
Iodine value, particle size, strength, moisture and packing can be discussed against the equipment and required outlet quality.
Please provide the stream composition, target contaminants, inlet and outlet limits, flow, temperature, humidity or pH, contact time and current equipment.
Service life depends on actual contaminant loading, competing compounds and operating conditions. Pilot testing and breakthrough monitoring provide the most reliable estimate.
