Gold Recovery Carbon specifications
Typical and configurable ranges, with the test method for each property.
Raw materialSelected high-hardness coconut shell · Uniform granular or water-polished activated carbon
| Raw material | Selected high-hardness coconut shell |
|---|---|
| Physical form | Uniform granular or water-polished activated carbon |
| Standard sizing | 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 |
| Custom manufacturing | 6x12, 6x16 or 8x16 sizing, iodine value, hardness, abrasion, ash, pre-treatment, water polishing and mine-specified gold adsorption testing. |
Iodine value alone does not qualify a gold-recovery carbon. Circuit-specific adsorption kinetics, capacity, hardness, abrasion and particle retention should be evaluated together. Final guaranteed values and test methods must be agreed in the order specification.

Where Gold Recovery Carbon is used
Typical applications and process selection checks.
-
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.

Gold Recovery Carbon sourcing questions
Answers use the same values as the tables on this page.
Which mesh is used for CIP or CIL?
Common directions include 6x12, 6x16 and 8x16 mesh, but screen aperture, transfer equipment and attrition conditions determine the final contract range.
Why are hardness and abrasion important?
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.
Can project test samples be supplied?
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.
