As a biomass multi-generation demonstration enterprise with 27 years of deep expertise in the activated carbon sector, China Huajing has specifically developed the Tailings Gold Recovery Apricot Shell Carbon to address critical pain points in gold tailings recovery. Utilizing premium apricot shells and leveraging a network of 16 specialized activation furnaces alongside advanced gasification-synergy processes, we have engineered a specialized adsorption carbon perfectly tailored for continuous mining operations. This product resolves common industry challenges—such as slow adsorption rates, susceptibility to pulverization, low recovery efficiency, and high material loss—thereby providing a robust and stable solution for the recovery of precious metals from gold tailings and the compliant treatment of mining wastewater.
Our product features high mechanical strength and exceptional abrasion resistance, ensuring it remains intact and resists pulverization even under rigorous conditions, making it ideally suited for continuous recovery processes. Backed by an annual production capacity of 40,000 tons, over 30 national patents, and a comprehensive, end-to-end quality control system, Huajing Activated Carbon guarantees a stable supply. We also offer customization options for specific performance parameters to meet unique operational needs, empowering mining enterprises to boost recovery efficiency and reduce operation and maintenance costs. Consequently, it stands as the preferred specialized adsorption material for the treatment of gold mining tailings.

Product Development Background

The loss of precious metals within gold mining tailings—coupled with pollutant levels exceeding regulatory limits—represents a pervasive challenge across the mining industry. Conventional coal-based activated carbons often suffer from poor adsorption selectivity and insufficient mechanical strength; under the abrasive flow of mineral slurries, they are prone to pulverization, which can lead to pipeline blockages. This not only results in the loss of valuable precious metals but also drives up operation and maintenance costs. In collaboration with Nanjing Forestry University and the Academician Workstation at the Chinese Academy of Forestry, China Huajing has optimized the pore structure and mechanical strength of its activated carbon specifically for tailings recovery environments. The resulting Tailings Gold Recovery Apricot Shell Carbon strikes an optimal balance between high adsorption capacity, exceptional abrasion resistance, and high operational adaptability. It has already been successfully and stably deployed across numerous gold mining enterprises in China, demonstrating a 10–15% increase in precious metal recovery rates and a reduction of over 30% in carbon material loss.

Core Performance Advantages

1. Raw Material and Process Advantages
Utilizing locally sourced, hard apricot shells from Chengde—characterized by a dense fibrous structure—our product undergoes physical activation via high-temperature steam (>900°C). No chemical additives are used, ensuring zero heavy metal residues. The pore distribution is precisely tailored to the requirements for adsorbing gold ions; consequently, its specific surface area and adsorption sites far exceed those of ordinary fruit-shell activated carbons. Employing Huajing’s integrated process for carbon, heat, and fertilizer co-production, the activation temperature is precisely controllable, guaranteeing stable performance for every batch of apricot-shell activated carbon used in tailings recovery, with batch-to-batch variation kept within ≤5%.

2. Adsorption and Operational Advantages
Rapid adsorption kinetics allow for the swift capture of gold-cyanide complex ions present in tailings liquid. High adsorption capacity ensures that the single-pass saturation adsorption volume exceeds industry standards. Low bulk density reduces the cost associated with packing adsorption columns. With a mechanical strength of ≥90%, the material withstands the agitation of mineral slurries and the scouring effects of backwashing; it resists pulverization and screen clogging during long-term use, making it fully compatible with the entire tailings recovery process in both Carbon-in-Pulp (CIP) and Heap Leaching operations.

3. Compatibility and Environmental Advantages
Resistant to acid and alkali corrosion, the material adapts effectively to complex mineral slurry water chemistries and demonstrates strong resistance to interference from organic substances. A low ash content (≤10%) minimizes the leaching of impurities, thereby preventing secondary pollution. Furthermore, the material is regenerable and recyclable, reducing material procurement costs for enterprises while fully aligning with the requirements for green mining production.

Production Process and Quality Control

1. China Huajing’s Tailings Gold Recovery Apricot Shell Carbon is manufactured through a fully standardized process:
Apricot shell screening and impurity removal → Low-temperature carbonization → High-temperature steam activation → Multi-stage screening → Air classification (fines removal) → Comprehensive quality inspection → Sealed packaging.
2. Production stages are equipped with online monitoring systems that allow for real-time regulation of activation furnace temperatures and steam flow rates. Every product batch undergoes rigorous testing for core indicators—such as particle size, iodine value, and mechanical strength—and is accompanied by a third-party quality inspection report, ensuring that 100% of outgoing products meet or exceed quality standards.
3. Our company holds over 30 national patents and has been designated a "National Forestry Standardization Demonstration Enterprise." Our production process was awarded the First Prize in the Liang Xi Forestry Science and Technology Awards, underscoring our industry-leading technical capabilities.

Usage and Maintenance Recommendations

1.Prior to loading, the material must be sieved to remove fines, thereby preventing fine particles from clogging the pipelines.
2.Maintain a tailings flow rate of 0.5–1.5 m/h to ensure adequate adsorption contact time.
3.Periodically sample and test the adsorption performance; if the iodine value drops below 700 mg/g, regeneration or replacement is recommended.
4.Store in a dry, well-ventilated area; keep sealed to prevent moisture absorption. Avoid co-storage with oils or organic substances to prevent premature adsorption deactivation.
