Another full container of coconut shell activated carbon heading to our repeat client in Egypt — 6×12 mesh, iodine 1100+, built for CIL gold circuits.
We just finished loading 28 tons of coconut shell activated carbon for gold recovery — destination Alexandria, Egypt. This is not a first order. This client has been buying from us for over three years, and every shipment follows the same spec: 6×12 mesh, iodine 1100+ mg/g, hardness 98%+. They run a CIL gold circuit and the carbon performs.

Three years, multiple containers. No drama. That's the short version.
The longer version: their mine runs a CIL circuit processing sulfide ore. They need carbon that holds up through 5+ reactivation cycles without falling apart. Our coconut shell carbon at 98.5%+ hardness does that. They tested three Chinese suppliers before settling on us — the other two had hardness issues after the third reactivation.
Price matters too. We're factory-direct with no middlemen, so they get a landed cost that's 30–40% below what they were paying their previous European-brand supplier. Same performance, significantly less money.
6×12 mesh — This is the standard particle size for CIL and CIP circuits. Large enough to be retained on inter-stage screens (typically 0.6–0.8 mm aperture), small enough for fast gold adsorption kinetics. Finer mesh like 8×16 gives faster kinetics but higher screen losses. For most African CIL plants, 6×12 is the sweet spot.
Iodine 1100+ mg/g — Higher iodine number means more micropore volume, which translates directly to higher gold loading capacity. At 1100+, this carbon typically achieves 25–30 mg Au/g carbon in a well-run CIL circuit. The client's plant data confirms this.
Hardness 98%+ — Gold recovery carbon takes a beating. It gets pumped between tanks, screened, eluted at 130°C, and thermally reactivated at 700°C — repeatedly. Low-hardness carbon generates fines, and fines mean gold losses. At 98%+ ball-pan hardness, our carbon survives 5–8 reactivation cycles with less than 3% mass loss per cycle.
Ash <3% — Low ash means fewer inorganic impurities that can interfere with gold adsorption and elution efficiency. Coconut shell naturally has lower ash than coal-based carbon, which is one reason it dominates the gold mining carbon market.

Every batch goes through our in-house lab before it leaves the factory:
• Iodine number per ASTM D4607 — tested on composite sample from every production lot
• Ball-pan hardness per ASTM D3802 — minimum 98%, reject below 98%
• Apparent density per ASTM D2854 — target 0.48–0.52 g/cc
• Moisture, ash, and particle size distribution — standard QC panel
• Gold activity test (optional) — K-value and R-value per industry method
This order was packed in 25 kg PP woven bags with PE inner liner, . We also offer 500 kg and customized bags or mines that prefer bulk handling.
28 tons fits neatly into one 40-foot container. Loaded at our factory, trucked to Nansha port in Guangzhou, and shipped direct to Alexandria. Door-to-port transit is about 20–25 days, depending on the shipping line and whether there's a transshipment stop.
We handle all export documentation: commercial invoice, packing list, COA, fumigation certificate, and bill of lading. CIF or FOB — your choice.
Tell us your mesh size, iodine target, and annual volume. We'll send you a spec sheet, pricing, and free samples within 24 hours.
Q: What is the MOQ for gold recovery activated carbon?
A: Standard MOQ is 1*20 FCL (13 tons). For first-time buyers, we can arrange a 1-ton trial shipment for testing. Free 1 kg samples available for lab evaluation.
Q: What is the lead time from order to shipment?
A: Production takes 7–10 days for standard gold recovery grades. Container loading and customs clearance add 3–5 days. Ocean freight from Nansha to Alexandria is approximately 20–25 days.
Q: Can you customize the carbon specs for our mine?
A: Yes. We adjust iodine number (1000–1200 mg/g), mesh size (6×12, 6×16, or 8×16), and hardness targets based on your CIP/CIL circuit requirements. Send us your current carbon spec sheet and we'll match or improve it.
Q: What payment terms do you accept?
A: T/T (30% deposit, 70% against B/L copy) for new clients. L/C at sight for orders above $50,000. Repeat clients may qualify for open account terms.
Q: Do you provide SGS pre-shipment inspection?
A: Yes. We support SGS, Intertek, or Bureau Veritas pre-shipment inspection on every order. The inspection report and COA are sent before the vessel sails.
