84 Tons Gold Recovery Carbon Shipped to Sudan — CIP Repeat Order, 3 × 40ft Containers

Order Summary

Background: A Client Who Came Back

Earlier in 2026 this client placed their first order with us — 56 tons of coconut shell gold recovery carbon for a CIL section of their plant. Before that order, they ran a side-by-side comparison of our carbon against a well-known competing brand, testing iodine value, hardness, CTC activity, and K value. The numbers matched. The price was lower. They shipped.

After running our carbon through their CIL circuit for several months, they came back with a second requirement: a CIP expansion. The CIP section needed a higher-kinetics grade — specifically iodine ≥ 1100 mg/g — to match the faster gold adsorption cycle typical of carbon-in-pulp operation. They specified HojeeGold CG33 and ordered 84 tons across three containers.

Repeat orders are a different kind of proof than a first inquiry. The client has already seen the carbon in operation, compared actual recovery data against their baseline, and decided the performance justifies continuing with the same supplier. The increased volume — from 56 to 84 tons — reflects a circuit expansion, not just a restock.

The Sudan client visited our factory before the first order. After receiving the 56-ton shipment, they sent confirmation: “Activated carbon works well. This quality is worthy of our next order.”

CIP vs CIL: Why the Grade Changed

In a CIL (carbon-in-leach) circuit, activated carbon is added directly to the leach tanks. Gold adsorption and cyanide leaching happen simultaneously, so the carbon operates in a slurry with active leaching chemistry. Residence time is longer. The emphasis is on elution compatibility and R value (retentivity).

In a CIP (carbon-in-pulp) circuit, leaching is completed first, and the carbon is introduced afterward to a clarified slurry with high gold-in-solution concentration. The contact time per tank stage is shorter. What matters most here is the K value — the rate at which gold loads onto carbon under AARL test conditions. A higher iodine value correlates with more available micropore surface area and faster adsorption kinetics.

That is why this client stepped up from CG32 (iodine ≥ 1050 mg/g) for CIL to CG33 (iodine ≥ 1100 mg/g) for the CIP section. The difference is not dramatic on paper, but in a CIP circuit running at high throughput, the faster kinetics translate directly to higher gold recovery per ton of carbon.

Coordinating 3 Containers: What Bulk Delivery Looks Like

CG33 granules tested in the lab before packing — iodine ≥1100 mg/g, hardness ≥99%, 6×12 mesh. One COA covers all three containers.

An 84-ton order is a bulk production commitment, not a warehouse pick. All three containers come from the same production batch — one batch, one COA, one quality baseline. This matters because inter-container variation is a real risk when suppliers split large orders across different production runs or blend batches to hit volume.

Each container holds approximately 28 tons net weight, packed in 550 kg FIBC jumbo bags. Fifty jumbo bags per container. The bags are labelled with batch number, grade, and test date. The packing list, weight certificate, fumigation certificate, and COA travel with the full Bill of Lading set. Port Sudan is the receiving point, with onward transport to the mine site inland.

From order confirmation to vessel departure was under three weeks. Typical vessel transit from a Chinese port to Port Sudan via the Red Sea runs 18–25 days. The client receives the full document package — COA, B/L, packing list, weight and fumigation certificates — before the vessel arrives, so they can clear customs without waiting at port.

What This Order Tells a Buyer Evaluating Suppliers

If you are sourcing gold recovery carbon for the first time, a case like this answers a specific question: can this supplier deliver at scale, consistently, after the first order?

A first order tells you about initial quality. A repeat order at higher volume tells you about supply reliability, production consistency, and whether the relationship holds when the client has already paid once and has real operating data. This client expanded their order and their circuit with the same supplier. That is the signal.

The scale of 84 tons across 3 containers also demonstrates a specific logistics capability: coordinating a multi-container shipment from a single batch, clearing a Chinese export port, and delivering to a Red Sea destination on schedule. Not every supplier handles that process without introducing quality variation or booking delays between containers.

If your mine runs CIP and you are evaluating whether to trial a new carbon supplier, the relevant question is not just the spec sheet. It is whether the supplier has delivered that spec at bulk volume, to your region, for a client who came back.
