Gold Extraction-Grade Coconut Shell Activated Carbon from Kelin

Kelin coconut shell activated carbon is produced from mature coconut shells harvested from trees aged five years or older. This raw material naturally possesses a dense lignocellulosic structure that yields activated carbon with extremely high hardness and superior wear resistance. Through a carefully controlled manufacturing process—consisting of impurity removal, carbonization, steam activation, crushing, screening, air classification, and final re-screening—the resulting carbon achieves an optimal combination of: High microporous surface area Low ash content Excellent mechanical strength Uniform particle size distribution These characteristics make Kelin coconut shell carbon particularly effective for the adsorption of gold-cyanide complexes in aqueous solutions. Types of Activated Carbon for Gold Extraction Gold recovery operations typically require different carbon forms depending on the extraction method. The two most widely used varieties include granular activated carbon and pelletized (columnar) activated carbon. Granular Coconut Shell Activated Carbon for CIP and CIL Systems Kelin granular activated carbon is specifically engineered for Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) circuits, where carbon particles must withstand continuous agitation, slurry flow, and multiple regeneration cycles. The highly developed microporous structure of Kelin coconut shell carbon provides exceptional adsorption performance for gold cyanide complexes. Performance Advantages Extremely high abrasion resistance for extended service life Low platelet...
