Huamei supplies granular activated carbon made from coconut shells through carbonisation and steam activation. Select the product series and grade for the intended application, and review the relevant specifications and technical documents.
After rigorous screening and washing, they undergo crushing, carbonisation and high-temperature steam activation processes to produce the final product, which typically takes the form of black granules. Its characteristics include a highly developed microporous structure, adsorption capacity, high hardness, and low ash content.
It is widely used in the recovery of gold and other precious metals, as well as in the purification of pure water, municipal drinking water treatment, water filter cartridges, air purification, cigarette filters and as a catalyst support.
This product is specifically designed for gold recovery processes such as carbon-in-leach (CIL), carbon-in-pulp (CIP) and carbon-in-column (CIC). Advantages of the HMGOLD™ series of coconut shell activated carbon:
Şartname
Made from 100% natural coconut shells and treated with high-temperature steam activation. It features a highly developed microporous structure and a vast specific surface area, for applications involving residual chlorine and selected organic contaminants in water. Suitability for specific contaminants, including metals, must be confirmed for the selected grade against water chemistry, contact conditions and treatment tests. It is widely used in drinking water purification, industrial water treatment, wastewater treatment and domestic water filtration cartridges.

Challenge: This gold mine, which utilises the CIL process, faced significant gold losses due to the generation of carbon dust. The existing activated carbon lacked sufficient hardness and fractured during agitation, resulting in soluble gold being lost with the tailings.
Solution: The mine switched to HMGOLD™ 7000 high-hardness activated carbon (hardness ≥99%) and optimised the adsorption cycle.
Results: The client’s carbon consumption has now been reduced by 20%, gold content in tailings has decreased, and annual gold recovery rates are projected to increase by approximately 8%. The client has placed four repeat orders.

Challenge: The water treatment plant faced issues with seasonal odours and organic pollutants in the source water. Its existing filtration system was unable to effectively remove these contaminants, leading to complaints from residents.
Solution: An activated carbon filter packed with HMG-CS™1100 was installed downstream of the sand filter.
Results:
Chlorine removal rate in treated water >95%
Odours completely eliminated; COD reduced by 60%
Water quality meets drinking water standards

We can customise the bags according to our customers’ requirements.
The HMGOLD series for gold recovery covers iodine number grades from 1050 to 1200 mg/g. The HMG-CS series for water treatment covers grades from 900 to 1200 mg/g. Refer to the selected grade’s specifications; iodine number alone does not establish gold recovery performance. Contact us to discuss particle size, pH and other requirements.
Attrition produces carbon fines that can carry adsorbed gold out of the recovery circuit. Durable granules help limit fragmentation and the loss of gold-bearing carbon fines. Our products have an attrition rate of ≤2%; review the applicable test method and selected grade specification alongside particle-size distribution and your plant’s retention screens.
Yes, we provide free samples (1–2 kg) to our customers. You only need to pay the shipping costs. Samples will be dispatched within 2 working days. Please contact us to request a sample.
We strictly adhere to the ISO quality management system. Every batch of product undergoes laboratory testing to verify the iodine value, hardness and other parameters.
