Activated Carbon for Gold CIP, CIL and CIC Recovery
In gold carbon-in-pulp (CIP), carbon-in-leach (CIL) and carbon-in-column (CIC) systems, activated carbon adsorbs dissolved gold cyanide complexes from process slurry or solution. Gold plants need carbon that can load gold efficiently while resisting abrasion, fines generation and screen losses during continuous operation.
YuXing coconut shell activated carbon is selected for high hardness, stable particle size distribution and strong micropore adsorption capacity. These properties help mines control carbon consumption, maintain adsorption efficiency and reduce operating losses caused by broken carbon and carbon fines.
Before selecting a grade, review the mesh size, iodine value, hardness, ash content, moisture, attrition performance and batch COA. For mesh selection details, see the 6×12 vs 8×16 activated carbon guide.
How Coconut Shell Activated Carbon Works in Gold Recovery
- Gold is dissolved into cyanide solution during leaching.
- Activated carbon contacts the slurry or solution in adsorption tanks or columns.
- Gold cyanide complexes are adsorbed into the micropores of the carbon.
- Loaded carbon is separated from the circuit and sent for elution.
- After regeneration, suitable carbon can be returned to the adsorption circuit.
Carbon performance is affected by ore type, slurry density, residence time, cyanide concentration, competing organics, carbon concentration, particle size and regeneration conditions. That is why procurement should compare actual batch specifications rather than relying on product name alone.
How to Choose Mesh Size
6-12 mesh activated carbon is commonly used in gold CIP and CIL plants because it balances adsorption rate, screen retention and abrasion resistance. Other mesh grades can be selected depending on circuit design, screen aperture, carbon movement, contact time and operating preference.
| Selection Factor | Why It Matters |
|---|---|
| Mesh size | Affects adsorption speed, tank retention, screening efficiency and carbon loss. |
| Iodine value | Indicates micropore adsorption capacity for gold cyanide complexes. |
| Hardness / attrition | Controls fines generation and carbon replacement cost. |
| Ash and moisture | Influence carbon purity, handling and effective dry weight. |
| Batch COA | Confirms actual supplied quality before shipment or repeat orders. |

Frequently Asked Questions
What mesh size is used for gold recovery activated carbon?
Gold CIP and CIL plants commonly use 6-12 mesh coconut shell activated carbon. Other grades such as 8-16 mesh can be selected according to screen size, tank design, solution flow and operating preference.
What iodine value is recommended for gold recovery?
YuXing supplies coconut shell activated carbon with iodine value options from 900-1300 mg/g. Higher iodine value generally indicates stronger micropore adsorption capacity, but hardness, attrition and particle size should also be checked.
How does activated carbon recover gold in CIP/CIL?
Activated carbon adsorbs dissolved gold cyanide complexes from leach slurry or solution. Loaded carbon is separated and sent to elution, then regenerated carbon may return to the adsorption circuit.
Why is coconut shell activated carbon preferred in gold mining?
Coconut shell activated carbon typically provides high hardness, low ash and strong abrasion resistance, helping reduce fines, carbon loss and unstable adsorption performance in continuous gold recovery circuits.
What specifications should buyers check before bulk purchase?
Buyers should check mesh size, iodine value, hardness, ash, moisture, bulk density, attrition result, packaging and batch COA before confirming bulk purchase.
Can YuXing provide TDS, MSDS and COA?
Yes. YuXing can provide TDS, MSDS and batch COA for technical review, procurement approval, customs clearance and quality confirmation.
