900 Iodine Value Apricot Shell Carbon for Gold Recovery

Leveraging years of experience in activated carbon manufacturing—combined with deep insights into real-world gold mining applications—Huajing China has spent years developing this specialized 900 Iodine Value Apricot Shell Carbon for Gold Recovery. This product is manufactured using natural wild apricot shells sourced from premium production regions in Northeast China. The unique distribution of lignin and cellulose within these shells, following high-temperature steam activation, results in a highly developed pore structure dominated by mesopores (2–50 nm).
This specific structural characteristic achieves a perfect molecular-level match with gold cyanide complexes [Au(CN)₂⁻], ensuring that these gold complexes can rapidly and efficiently penetrate the internal pore channels and be effectively captured. By choosing this product, you gain access to a solution that strikes an ideal balance between adsorption kinetics and adsorption capacity—making it particularly well-suited for processing low-grade ores or for projects with strict cost-control requirements.

Core Features

1. Optimized Pore Structure for More Efficient Adsorption: Compared to coconut shell activated carbon, our 900 Iodine Value Apricot Shell Carbon for Gold Recovery features a significantly higher ratio of mesopores, endowing it with faster adsorption kinetics. In CIL processes, this translates to shorter adsorption times, thereby boosting the overall processing capacity of the production line. Its stable iodine adsorption value of over 900 mg/g provides a robust foundation for the efficient recovery of gold.
2. Exceptional Mechanical Strength to Reduce Operational Costs: Addressing the inherent challenge of the relatively lower mechanical strength of raw apricot shells, we employ an advanced, proprietary granulation and strengthening process. This technique elevates the product's mechanical strength to over 90%, ensuring durability and minimizing carbon attrition during processing. In continuously agitated mineral slurries, our product effectively resists abrasion and minimizes the generation of fine particles, thereby reducing carbon tonnage losses and extending service life. This has a direct and significant impact on lowering your production costs per ton of gold.
3. Stable Bulk Density for Process Consistency: The product's bulk density is precisely controlled within the range of 0.48–0.58 g/mL. This ensures the uniformity and permeability of the adsorption bed, preventing channeling and short-circuiting phenomena, and guaranteeing the stability and predictability of the adsorption process.

Application Scenarios

Carbon-in-Leach (CIL): Directly added to gold-bearing sulfide mineral slurries, achieving efficient adsorption through continuous agitation. In a case study at a gold mine in China, our product successfully reduced the production cost per ton of gold from 87,000 RMB to 69,000 RMB, fully demonstrating its economic value.
Heap Leaching: Suitable for the recovery of gold from low-grade ores or tailings. Its powerful adsorption capacity effectively captures trace amounts of gold from the leaching solution, thereby boosting the overall recovery rate. Gold Tailings Recovery: For residual gold remaining in tailings, our product facilitates deep adsorption, enabling the maximization of resource utilization.

Quality Assurance

Raw Material Selection: We exclusively select high-quality apricot shells—characterized by their plumpness and low impurity levels—to ensure product quality right from the source.
Process Control: We utilize advanced rotary kilns for carbonization and activation, precisely controlling temperature, steam flow, and residence time to ensure that the pore structure of every granule of our 900 Iodine Value Apricot Shell Carbon for Gold Recovery reaches its optimal state.
Quality Inspection: We operate an industry-leading laboratory where every batch of product undergoes comprehensive testing for key parameters, including iodine value, mechanical strength, moisture content, and ash content.
Our quality control team conducts random sampling, employing both visual inspection and tactile assessment to evaluate the product's mechanical strength and adsorption potential, thereby ensuring that every outgoing shipment meets—or even exceeds—national standards.

FAQ

Q1: What is the difference between your 900 Iodine Value product and your 1000 Iodine Value product? A1: While the 900 Iodine Value product has a slightly lower adsorption capacity compared to the 1000 Iodine Value product, it offers a significant advantage in terms of cost-effectiveness. It is particularly well-suited for processing ores with relatively stable grades and where requirements for adsorption rates are not extremely stringent. We recommend that you conduct a comprehensive evaluation based on your specific ore grade, process conditions, and budget. Our technical team is available to provide you with free sample testing and product selection recommendations.
Q2: How do you ensure the product's abrasion resistance?
A2: Through a specialized granulation process, we have significantly enhanced the product's mechanical strength while preserving the natural pore structure of the apricot shells. Our 900 Iodine Value Apricot Shell Carbon for Gold Recovery boasts a strength rating of ≥98%; even under the continuous agitation typical of the CIL process, it exhibits an extremely low attrition rate, thereby effectively reducing your operational costs.
