High Hardness Coconut Shell Granular Activated Carbon for Gold Recovery,
Gold Refining & Gold Extraction | Factory Direct Supply
98%+ Wear Resistance, SGS Certified, Mass Export to Africa Mining Market
6-12 mesh, iodine value 1100-1200mg/g, CTC 55-60%, customized packaging
Yihang Gold Recovery Coconut Shell Granular Activated Carbon is specially engineered for gold extraction, gold refining and all precious metal leaching processes, made from premium natural coconut shell raw materials imported from Southeast Asia. As a professional activated carbon manufacturer, we adopt high-temperature steam activation technology to build abundant microporous structure, delivering ultra-high selective adsorption capacity for gold cyanide complex ions.
This metallurgical grade carbon meets strict mining industry standards with wear resistance above 98%, featuring low powdering rate, long service life and excellent regenerability, effectively cutting gold loss during CIP, CIL and CIC production lines.
We own an independent quality inspection department, implementing 3 rounds of strict testing in every single production procedure from raw material screening to finished goods packaging. All batches come with official factory qualification certificates and full COA reports, and the products have repeatedly passed third-party SGS testing to guarantee stable consistent performance.
Our gold extraction activated carbon gains wide recognition in Africa mining markets; we exported 2000 tons of coconut shell metallurgical activated carbon last year. Custom packaging and private brand OEM & ODM services are available to meet global distributors and mine operators’ personalized demands.

1,Gold Recovery & Gold Extraction Mining Main adsorbent for CIP (Carbon-in-Pulp), CIL (Carbon-in-Leach), CIC (Carbon-in-Column) gold leaching processes in gold mines across Africa, Southeast Asia and Central Asia. Rapidly capture gold cyanide complex from ore slurry to boost gold recovery rate.
2,Gold Refining Metallurgical Plant Used for precious metal separation, gold solution purification and gold elution circulation in large-scale gold refining factories, stable under long-cycle desorption & regeneration.
3,Small & Medium Gold Processing Workshops Applicable for heap leaching, agitation leaching and small fixed-bed gold extraction equipment, low abrasion reduces frequent carbon replacement cost.
4,Precious Metal Recycling Industry Adsorb trace gold from waste electroplating liquid, mineral tail water and recycled metal waste liquid for secondary gold recovery.
5,African Mining Operations ,Proven performance in harsh field conditions; widely used in Ghana, Tanzania, Mali, and other African gold-producing regions.
A: 1. Raw coconut shells are imported from Southeast Asia with thicker shell texture for higher hardness; 2. Independent QC lab with 3-time full inspection in all production links; 3. Hardness reaches over 98% to minimize carbon powder loss and gold waste; 4. All batches support SGS third-party testing and provide complete COA documents. We have stable supply experience serving African mining clients with 2000 tons annual export volume.
A: Yes. Every batch of our gold recovery activated carbon is equipped with factory outgoing qualification certificate and full COA report. We can arrange SGS third-party inspection before shipment and offer official SGS test documents upon client request.
A: Absolutely. We support OEM & ODM customized packaging, including 25kg woven bags, ton jumbo bags, small sample bags, and can print your own brand logo, company information and product specifications on packages as required.
A: Standard mesh options: 5×10 mesh (heap leaching), 6×12 mesh (CIP/CIL mainstream mining), 8×16 mesh (fixed column CIC refining). We can adjust particle size and technical indicators according to your mine production process.
A: Metallurgical gold extraction equipment runs with strong slurry stirring and repeated elution regeneration. Carbon with low hardness will break into fine powder, flow away with slurry and carry adsorbed gold, causing huge precious metal loss. Our ≥98% wear resistance greatly lowers carbon consumption and improves overall gold recovery efficiency.
A: We are professional coconut shell activated carbon manufacturer with stable annual output of metallurgical gold carbon above 2000 tons. Our products are highly popular in Africa gold mining markets, also widely shipped to Central Asia, Middle East and Southeast Asia mineral processing factories.
A: We provide small test samples free of charge; clients only need to bear the international freight cost. Samples carry complete test data to verify adsorption performance for your gold recovery & gold refining process.
A: Sealed packaging shelf life is 24 months. Store in dry, ventilated warehouse, avoid direct moisture and mixed storage with volatile chemical substances to prevent adsorption capacity decline.
