CAS 7440-44-0
Coconut Shell Activated Carbon
Granular and pelletized activated carbon from mature coconut shell — high hardness and attrition resistance, multi-stage de-dusting for minimal ash and fines, less gold lost during adsorption. Sized for CIP / CIL / CIC columns.
01Specifications
Specifications
| Raw material | Mature coconut shellShell matured over a long growth cycle to develop the hardness and attrition resistance the gold-mining environment demands. |
|---|---|
| Pore structure | Micro-porous — built to adsorb gold–cyanide complexes |
| Processing | Vee-wire screening + wind separation, with further de-dustingKeeps platelets and dust to a minimum, protecting recovery performance and downstream equipment alike. |
| Series | GAC (granular) ／ Pelletized (extruded) |
| Optional finish | Polished — rounded granulesResists edge-chipping under sustained agitation in CIP / CIL circuits, reducing fines generation over the carbon's service life. |
Values shown are representative specification values, not guaranteed values for any individual lot. Refer to the technical data sheet and lot certificate of analysis for binding figures.
Applications
- Carbon adsorption — CIP / CIL / CIC circuits
- General industrial adsorption duties
Packaging
- GAC — 25 kg/bag or 550 kg/bag
- Pelletized — 25 kg/bag or 500 kg/bag
