Activated Carbon for Gold Recovery
Compare gold-recovery carbon using adsorption, attrition and particle-size checks relevant to your circuit.
Gold Recovery — Application Overview
Carbon-in-pulp (CIP), carbon-in-leach (CIL) and carbon-in-column (CIC) circuits use granular activated carbon under different operating conditions. When evaluating a coconut shell carbon grade, compare gold adsorption, attrition and particle retention using tests relevant to the circuit.
How Carbon Is Used
Granular carbon adsorbs dissolved gold complexes in the relevant process solution. Carbon is then separated and processed within the recovery circuit. Compare samples using the circuit chemistry and agreed adsorption tests rather than relying on a general carbon specification.
Selection Priorities
Adsorption behavior
Review the test method, kinetics and loading data relevant to your solution.
Strength and retention
Assess attrition, particle-size distribution and loss through the selected screens.
Circuit handling
Include transfer, elution and regeneration conditions in the grade review.
Grade Parameters & Purchasing Brief
Specify the recovery circuit, screen size and current carbon grade. Compare gold adsorption, particle-size distribution and abrasion behavior under the same test conditions.
| Circuit type | CIP, CIL or CIC and relevant solution conditions. |
|---|---|
| Particle distribution | Mesh range, screening arrangement and fines limit. |
| Adsorption testing | Agreed kinetics or loading test and reporting method. |
| Mechanical checks | Hardness or attrition method and handling requirements. |
| Order documents | Grade identification, batch results and acceptance criteria. |
Industry Uses
CIP, CIL and column circuits place different demands on carbon. Retention screens, slurry conditions and regeneration influence the grade requirements.

Frequently Asked Questions
Is iodine value sufficient for selecting gold-recovery carbon?
Use gold-recovery tests and physical checks relevant to your circuit. A general adsorption index alone does not establish gold-loading or attrition performance.
What should I include in a sample request?
Send the circuit type, current mesh size, screen opening and acceptance tests for adsorption and abrasion. Include the trial charge, regeneration conditions, bulk quantity and delivery country. Attach the current grade specification or use our specification checklist to prepare the inquiry.
Plan Your Carbon Evaluation
For gold-recovery carbon supply, state the mesh size, order quantity and packing. Attach the current specification so offers can be compared on the same basis.
