Qizhong Chemical supplied 27.5 tons of 6–12 mesh coconut shell activated carbon to a customer in Egypt for gold recovery. The buyer specified an iodine value of 1200 mg/g and placed particular emphasis on three quality requirements: low ash content, clean carbon free of dust and contamination, and uniform particle size.
These requirements are not special conditions for a single order. Low ash, cleanliness, and particle-size uniformity are the baseline production requirements Qizhong applies to activated carbon for gold recovery. For this shipment, quality was controlled at each production stage and the finished batch passed factory inspection before delivery.
Customer Requirements
6–12 mesh at an iodine value of 1200 mg/g is a standard size and activity level for gold recovery carbon. Beyond these figures, the customer confirmed three priorities for the order:
- Low ash content
- Clean carbon, free from dust and foreign matter
- Uniform particle size
In gold adsorption circuits, these points matter alongside iodine value: high ash occupies pore volume and reduces effective adsorption capacity, dust and fines are lost with the slurry and can disturb screening, and uneven particle size leads to inconsistent adsorption behavior and faster loss from abrasion. This is why experienced gold carbon buyers confirm ash, cleanliness, and particle-size distribution in addition to activity indicators.

Production, Quality Control, and Delivery
Low ash, cleanliness, and uniform particle size are baseline requirements for this product line, not conditions negotiated per order. Production for gold recovery carbon is controlled from raw material selection through carbonization and activation, screening and grading, and dust removal. The finished batch is inspected before it leaves the factory.
The 27.5-ton consignment was released for loading after completing factory inspection against the confirmed specification, then shipped to the customer in Egypt.
What This Means for Gold Carbon Buyers
When sourcing activated carbon for gold recovery, iodine value alone is not a complete basis for comparison. Buyers should also confirm ash limits, cleanliness requirements, and particle-size distribution, and ask how each batch is inspected before shipment. For application context, see our gold recovery activated carbon applications page.
Frequently Asked Questions
Why does gold recovery activated carbon need low ash content?
Ash occupies internal pore volume without contributing to adsorption, which reduces effective capacity in gold adsorption circuits. Controlling ash is therefore a standard quality requirement for gold recovery carbon, alongside iodine value and particle size.
Is 6–12 mesh with iodine 1200 mg/g a standard gold recovery grade?
6–12 mesh coconut shell carbon is a common size for gold recovery applications, and iodine values in this range are typical for grades used in carbon-in-leach and carbon-in-pulp circuits. The exact specification should always be matched to the operating conditions of the individual plant.
How is batch quality verified before shipment?
For this order, the batch passed factory inspection against the confirmed specification before loading. Buyers who require additional verification can request batch test documentation or arrange third-party pre-shipment inspection when placing the order.
