Typical sourcing range
Specifications buyers can use to prepare an RFQ
These are common or configurable manufacturing ranges, not a batch guarantee. Final acceptance values, methods and tolerances are confirmed in the signed product specification and batch COA.
| Raw material | Selected high-hardness coconut shell |
|---|---|
| Form | Uniform granular or water-polished activated carbon |
| Particle size | Common sourcing directions: 6x12, 6x16 or 8x16 mesh; final range must match the CIP/CIL equipment |
| Iodine value | Common target: >=1,000 mg/g; premium directions may reach 1,000-1,200 mg/g |
| Hardness | Common target: >=97%, together with abrasion and fines control |
| Ash | Common target: <=5% |
| Moisture | Typically <=5% |
| pH | Typically 8-11 |
| Apparent density | Typical reference range: 480-550 g/L |
| Gold-specific testing | Adsorption rate, loading capacity, K/R values or a mine-specified CIL bottle-roll test |
Send these fields for grade matching
Circuit type, screen aperture, slurry or solution conditions, target mesh, hardness and abrasion criteria, sample-test method, quantity and packing.
Application fit
Common use directions
- Carbon-in-pulp (CIP)
- Carbon-in-leach (CIL)
- Carbon-in-column (CIC)
- Heap-leach pregnant-solution treatment
Custom manufacturing
Fields that can be reviewed
6x12, 6x16 or 8x16 sizing, iodine value, hardness, abrasion, ash, pre-treatment, water polishing and mine-specified gold adsorption testing.
Test-method note: Iodine value alone does not qualify a gold-recovery carbon. Circuit-specific adsorption kinetics, capacity, hardness, abrasion and particle retention should be evaluated together.
Grade selection
How to specify Gold Recovery Carbon for a bulk order
Use the application, equipment and agreed test methods to turn a typical product range into a contract specification.
Selection factors
- Match 6x12, 6x16 or 8x16 mesh to the circuit screens, transfer equipment and carbon-retention conditions.
- Review hardness together with abrasion loss and fines generation because a single hardness value does not describe circuit losses.
- Compare adsorption rate and loading capacity under representative mine-solution conditions rather than iodine value alone.
- Agree the sample method, acceptance values and scale-up criteria before using a test result for a bulk purchase.
Quality checks to discuss
- Contracted mesh distribution and oversize/undersize limits
- Hardness, abrasion loss and fines generation
- Ash, moisture and apparent density
- Gold adsorption kinetics or mine-specified bottle-roll test
- Batch COA and retained sample when agreed
Contract boundary: The signed specification identifies guaranteed values, methods, sampling and tolerances. Website ranges remain sourcing references.

FAQ
Gold Recovery Carbon purchasing questions
Common directions include 6x12, 6x16 and 8x16 mesh, but screen aperture, transfer equipment and attrition conditions determine the final contract range.
Carbon losses, fines generation and screen retention directly affect circuit operation. A hardness number should be reviewed together with abrasion loss and the agreed test method.
Yes. Standard samples are normally free, while larger 2-5 kg project samples for bottle-roll or column testing are reviewed against the project and courier requirements.
