DESCRIPTION
Explore description details to support your evaluation.
Gold recovery circuits place unusual demands on activated carbon. In carbon-in-leach (CIL) and carbon-in-pulp (CIP) operations, coconut shell activated carbon is a recognized option because its hard, dense structure suits repeated adsorption and elution cycles. Sanniu Carbon supplies a coconut shell granular series intended for gold adsorption duty, with batch values confirmed before quotation.
The material adsorbs dissolved gold from cyanide leach slurries onto the carbon surface. Coconut shell carbon is favored here because it balances a developed pore structure with mechanical strength. High hardness helps the granules resist abrasion, screening and transfer in CIL and CIP tanks, where fines can mean carbon loss. Bulk density matters for sizing carbon inventory and slurry movement in each tank.
Selection should follow the circuit rather than a single headline number. Iodine value and methylene blue adsorption describe the adsorption capacity of the series, while hardness and particle size relate to retention and screening in slurry. The particle size cut should be agreed against the plant's screen configuration so carbon stays in the circuit rather than reporting to tailings. Published ranges describe the series; the actual batch result is confirmed against the agreed test method.
To discuss a fit, share the intended CIL or CIP duty, target particle size cut, expected carbon concentration or flow, and quantity under consideration. Our team will confirm the applicable specification and batch data before any commercial commitment.

Common questions from buyers and metallurgists specifying coconut shell activated carbon for carbon-in-leach and carbon-in-pulp gold recovery circuits.
Which factors matter most when choosing carbon for a CIL/CIP circuit?
Start with the duty, not the datasheet alone. In carbon-in-leach and carbon-in-pulp circuits, carbon is repeatedly contacted, screened and transferred, so attrition resistance and a particle cut that suits your screens matter as much as adsorption capacity. Confirm the leach or pulp conditions, target loading, screen aperture and make-up carbon rate with your metallurgist, then match the grade and size cut to that duty. Our coconut shell granular series is offered for gold recovery circuits, with batch values confirmed against the agreed specification.
How is hardness relevant to carbon losses in a CIL/CIP plant?
Hard carbon resists rounding and fines generation as it moves through adsorption tanks, elution and regeneration. Fines that pass the screens leave with the slurry and represent both a carbon loss and a possible loading loss. Our granular series carries a ball-pan hardness reference minimum of 95 for CIL/CIP attrition duty, with the batch value confirmed. Hardness is one input to your loss estimate, not a guarantee of plant performance; actual losses also depend on handling, pumping, screening practice and regeneration conditions.
Which particle size should we specify for carbon-in-pulp screens?
Select the cut so that the carbon is retained on your interstage screens while still fluidising and transferring cleanly. The listed particle size range for this series is 4 to 40, with the exact cut agreed per order. State your screen aperture, slurry flow and any existing carbon size when you enquire, and we will check the requested cut against the agreed specification. A cut that is too coarse may settle poorly; one that is too fine may pass screens, so the choice should follow the circuit design.
Can the moisture and bulk density figures be confirmed per lot?
Yes. Moisture as packed is quoted as a 3 to 10 range and bulk density as 0.45 to 0.55 g/cm³ for the granular series; both are confirmed for the actual lot. Bulk density helps you estimate bed and slurry sizing, while moisture affects the as-received mass you pay for. The values on the product specification table are series ranges, not a promise for every bag. Ask for the current batch figures and the agreed test method with your quotation request.
How should we handle sampling, elution testing and batch documentation?
Agree the sampling and test plan before shipment. Ask for the certificate of analysis covering the metrics on the frozen specification, and confirm which third-party documents apply. For elution and regeneration evaluation, test the actual delivered lot under your circuit conditions rather than relying on a generic curve. We can discuss test quantities and documentation as part of the enquiry; price, available quantity and delivery timing are confirmed in the written quotation or order. Sample reports only describe the samples tested.
