Coconut Shell Activated Carbon for Gold Recovery

WIMICA (Hebei) Industrial Co., Ltd is a professional manufacturer and exporter specializing in coconut shell activated carbon for gold recovery. By integrating manufacturing, quality control, and international export services, we provide reliable activated carbon solutions to mining companies and distributors worldwide.

Our production process begins with carefully selected premium coconut shells, which are carbonized and activated under precisely controlled conditions to develop a highly porous structure with excellent adsorption capacity. Each production batch undergoes comprehensive quality inspection, including iodine number, hardness, ash content, moisture content, and particle size distribution, ensuring that every shipment meets customer specifications and industry requirements.

Unlike ordinary activated carbon used for water purification or air treatment, WIMICA coconut shell activated carbon is specifically engineered for gold recovery processes. Its high mechanical strength minimizes carbon loss during circulation, while its well-developed pore structure enables rapid adsorption of gold complexes from cyanide solutions. Low ash content also helps reduce impurities introduced into the processing system, contributing to more stable plant operation.

With years of manufacturing and export experience, WIMICA has supplied coconut shell activated carbon to customers involved in gold mining projects across Africa, Asia, South America, and other international markets. Our products are suitable for newly commissioned gold processing plants as well as existing operations seeking stable adsorption performance and consistent product quality.

Performance Verification

Gold Adsorption Performance

The primary function of coconut shell activated carbon in gold recovery is to efficiently adsorb dissolved gold complexes from cyanide leaching solutions. WIMICA Coconut Shell Activated Carbon is manufactured with a highly developed microporous structure, providing a large internal surface area that facilitates rapid and stable adsorption during both CIP (Carbon in Pulp) and CIL (Carbon in Leach) operations.

Each production batch is manufactured under controlled activation conditions to maintain consistent pore distribution and adsorption characteristics. Before shipment, key quality indicators such as iodine number, particle size distribution, hardness, ash content, and moisture are inspected to ensure compliance with customer specifications.

The combination of high adsorption capacity and stable physical properties enables mining operations to maintain efficient carbon loading while reducing unnecessary carbon replacement during production.

Hardness and Abrasion Resistance

During gold recovery, activated carbon continuously circulates through adsorption tanks, transfer pumps, screens, and regeneration systems. Carbon with insufficient mechanical strength may generate excessive fines, resulting in carbon loss and reduced recovery efficiency.

WIMICA Coconut Shell Activated Carbon is manufactured from premium coconut shell, naturally recognized for its excellent hardness. With a hardness of not less than 98%, the product demonstrates excellent resistance to abrasion during continuous circulation, helping mining operations reduce carbon loss and maintain stable production performance.

High hardness also contributes to longer service life, allowing activated carbon to withstand multiple adsorption and regeneration cycles while maintaining its structural integrity.

Low Ash Content and Product Purity

Ash content is an important indicator influencing the performance of activated carbon used in gold recovery. Lower ash levels help minimize the introduction of inorganic impurities into the adsorption system and support more stable operating conditions.

WIMICA Coconut Shell Activated Carbon is manufactured under carefully controlled production conditions to maintain an ash content of 3% or below. The use of selected coconut shell raw materials and strict process control contributes to consistent product purity and dependable adsorption performance.

Stable product quality is especially important for mining companies seeking reliable long-term operation and predictable production results.

Uniform Particle Size Distribution

Uniform particle size plays an important role in maintaining efficient carbon movement and minimizing carbon loss in adsorption systems.

WIMICA supplies multiple particle sizes, including 4×8 Mesh 6×12 Mesh, 6×16 Mesh, and 8×16 Mesh, allowing customers to select the most suitable specification according to their processing equipment and operating conditions.

Consistent particle size distribution improves screening efficiency, promotes uniform slurry flow, and supports stable adsorption performance throughout the gold recovery process.

Comparison with Ordinary Activated Carbon

Compared with conventional activated carbon, WIMICA Coconut Shell Activated Carbon is specifically engineered for gold recovery applications. Premium coconut shell raw materials, combined with controlled activation technology, provide higher mechanical strength, lower ash content, and a more developed pore structure, making it suitable for continuous operation in CIP and CIL gold recovery systems.

The optimized physical properties of WIMICA Coconut Shell Activated Carbon help reduce carbon loss during circulation while maintaining stable adsorption performance throughout the gold recovery process.
