Which Activated Carbon for Gold Recovery? — 3-Way Comparison
For CIP/CIL gold recovery, the carbon type decides how much gold you keep. Compare hardness, pore structure and suitability below.
| Carbon Type | Hardness | Pore Structure | Suitability for Gold (CIP/CIL) |
|---|---|---|---|
| ✔ Coconut Shell Carbon — BEST | ≥ 98% (extreme) | Micropores | ✔ Hard coconut-shell GAC for CIP/CIL circuits — selected for high hardness, low fines generation and good gold-loading capacity under suitable operating conditions |
| ⚠ Coal-Based Carbon | 80–90% (soft) | Mesopores | ⚠ Usually less suitable where maximum hardness and low fines are critical; selection depends on ore, circuit and attrition conditions |
| ✖ Wood-Based Carbon | < 70% (very soft, dusty) | Macropores | ✖ Usually not selected for CIP/CIL where mechanical strength and low fines are critical |
Three Specs That Drive Your Cost Per Ounce
Hardness = Make-Up Cost
A 2% difference in attrition can mean nearly a tonne of make-up carbon a year on a mid-size plant — before counting the gold carried away in the fines.
Iodine = Loading Rate
Consistent iodine 1000–1300 keeps your gold loading rate predictable, so elution and electrowinning stay on schedule.
Consistency = Planning
Documentation — See What We Ship With
Every order ships with a batch COA (Certificate of Analysis for the exact lot), TDS (technical data sheet), business license and SDS. Our quality management follows ISO 9001-aligned documented procedures; formal certification is in progress and will be published when issued. View a sample routine batch COA and our company documents — and test the delivered lot in your own lab.
Your circuit needs a defined tolerance band. We agree the release limits, test the lot with named methods and issue the exact-lot COA for review.
How is gold-grade carbon packed for export?
25 kg laminated export bags on shrink-wrapped pallets, or 500–1000 kg jumbo bags, container-ready. We can also arrange partial-container or consolidated loads for African buyers.
Can you supply evaluation samples before I order?
Yes. The standard 500 g sample is free. International courier charges are paid by the buyer; shipping within mainland China is included. Larger trial lots are quoted separately.
What is your production MOQ?
One 20 ft container (roughly 16–18 tonnes). For smaller first orders, ask about consolidated programs for West African destinations.
What data should be requested before a gold carbon quotation?
A comparable gold carbon quotation should state the circuit, application and required specification. Send the plant route, solution or pulp flow, gold tenor, temperature, pH, cyanide concentration, suspended solids and the carbon movement method. Specify mesh or particle-size distribution, acceptable fines, iodine band, hardness or abrasion limit, apparent density, moisture and ash. State the stripping method, acid-wash conditions and regeneration temperature, because these determine whether the carbon must survive repeated handling as well as adsorption. Ask how the supplier will sample the production lot, which ASTM or GB/T methods appear on the COA, whether a retained sample is available and how an off-spec result is handled. Finally, confirm packing, net weight, port, lead time and trial quantity. This information makes price comparisons meaningful and gives both sides an objective release specification. The agreed release criteria should follow the quotation.

How do you verify a batch COA?
Verify that the lot number, product grade and quantity on the COA match the bags, pallet labels and shipping documents. Check that each result states a method and an acceptance limit, especially mesh distribution, iodine number, ball-pan hardness or abrasion resistance, apparent density, moisture and ash. If R-value or K-value is reported, confirm the laboratory method and test conditions before comparing it with another supplier's number. Ask whether the sample is from the exact production lot, whether it is a single sample or composite, and whether a retained sample can be made available for re-test. Review the sign-off and date, then test critical values in your own laboratory or an agreed third party before approving repetitive supply. A COA is useful evidence only when it is traceable; a generic certificate with no lot link is not enough for batch release.
What should you send for a 6×12 gold carbon quotation?
A comparable 6×12 coconut shell activated carbon quotation should identify the circuit, destination port, quantity, required iodine and hardness limits, packing and delivery date. For CIP/CIL, send the solution or pulp flow, gold tenor, pH, cyanide concentration and suspended solids where available. Also state the interstage screen aperture or column design, acceptable fines, regeneration conditions and whether the first step is a 500 g sample, a 25 kg trial or a full container. YELI Carbon can then confirm the applicable grade, exact-lot COA route, packing, FOB or CIF scope and written release limits. Buyers can compare the 6×12 specification sheet and sample COA before requesting factory price and current production lead time.

Flexible start: tell us your target spec and quantity — we will quote FOB or delivery terms, confirm the grade, and arrange consolidated loads for West African destinations on request.
Compare Three Grades in One Sample Pack
Instead of guessing, test on your own liquor: our 3-grade sample pack ships three coconut shell GAC grades in one parcel — e.g. iodine 1000 / 1100 / 1200, each with its own COA and test method. Run a bench adsorption or small-column test, see which grade fits your pulp chemistry, then order the one that wins.
Spec Tolerances — Written Into Every Contract
Every order confirms tolerance limits for the delivered lot: iodine tolerance against the ordered grade, the agreed minimum hardness, the agreed moisture basis and limit, and the agreed fines range. If the delivered batch is off-spec, we replace it or credit you — that guarantee is in the contract, not just the brochure.
Lead Times & Delivery Proof
Sample packs ship within 3 working days by courier. Container orders: production 10–15 days from confirmed spec, then sea freight to West African ports (Lagos, Tema, Abidjan, Dakar) with typical transit 30–40 days. We provide the bill of lading, packing list and per-batch COA with every shipment — so your logistics team has full documentation from day one.
