1000 Iodine Value Apricot Shell Carbon for Gold Recovery

Huajing’s 1000 Iodine Value Apricot Shell Carbon for Gold Recovery embodies years of deep technical expertise accumulated within the field of activated carbon. It represents far more than a simple increase in iodine value; through the comprehensive optimization of raw materials, activation processes, and post-treatment technologies, it achieves a qualitative leap in adsorption performance. The product's surface is rich in oxygen-containing functional groups, which form stable coordination bonds with gold cyanide complexes. This significantly mitigates the risks associated with adsorption and desorption, ensuring the overall stability of the recovery process.

Key Features

1. Ultra-High Adsorption Capacity: Maximizing Gold Recovery
With an iodine adsorption value of ≥1000 mg/g and a specific surface area reaching 1000–1200 m²/g, this product possesses astonishing adsorption potential. Its maximum adsorption capacity can reach up to 5.8 kg of Au per ton of carbon. This means you can adsorb a greater quantity of gold using less activated carbon, thereby reducing both carbon procurement costs and subsequent desorption processing costs. 2. Dual-Mechanism Adsorption: Ensuring Process Stability The product captures gold cyanide complexes not only through physical adsorption (via Van der Waals forces) but also through chemical adsorption (via coordination bonds) facilitated by its surface functional groups. This dual mechanism ensures the robustness of the adsorption process, effectively minimizing the risk of premature desorption caused by process fluctuations, and guaranteeing a stable gold recovery rate. 3. High Desorption Rate: Boosting Operational Efficiency Under optimized conditions, our 1000 Iodine Value Apricot Shell Carbon for Gold Recovery achieves a desorption rate as high as 95.6%. This signifies that the gold adsorbed onto the activated carbon can be desorbed more efficiently and thoroughly, shortening the desorption cycle and improving equipment utilization—factors that directly translate into enhanced economic benefits for your operations.

Application Scenarios

CIL/CIP Processes for High-Grade Ores: For ores with high gold grades, our 1000 Iodine Value product rapidly and efficiently adsorbs gold from the ore slurry, preventing gold loss during processing and maximizing recovery yields.
Carbon-in-Pulp (CIP) Process: In the CIP process, activated carbon flows counter-currently against the ore slurry, placing higher demands on adsorption kinetics and capacity. Thanks to its superior performance, our product is perfectly suited to meet these rigorous process requirements.
Deep Desorption of Gold-Loaded Carbon: Its high desorption efficiency makes the gold stripping process significantly more effective—a feature particularly well-suited for modern gold mines utilizing pressurized or thermal desorption techniques.

Quality Assurance

1. Precision Activation
We employ an advanced computer-controlled system to regulate the temperature, steam pressure, and duration within our activation furnaces with micron-level precision. This ensures that the pore structure of every granule of our 1000 Iodine Value Apricot Shell Carbon for Gold Recovery achieves the optimal ratio of micropores to mesopores, thereby successfully attaining an Iodine Value exceeding 1000.

2. Enhanced Post-Processing
Through a unique acid-washing process, we effectively reduce the product's ash content and enhance its purity. Simultaneously, a specialized resin-reinforcement treatment not only boosts mechanical strength but also introduces a higher density of active functional groups to the surface, thereby enhancing chemical adsorption capabilities.

3. End-to-End Traceability
From raw material intake to finished product dispatch, we have established a comprehensive quality traceability system. Every product batch is assigned a unique batch number, allowing for full traceability back to its specific raw material lot, production date, critical process parameters, and quality inspection reports. This ensures the consistent stability and reliability of our product quality.
