Premium Activated Carbon for Gold Recovery – High-Efficiency Adsorption & Durability
Raw Material: Coconut Shell
Applications: Gold Recovery, CIP, CIL, CIC, Precious Metal Recovery
Keywords: Gold Recovery Activated Carbon, Coconut Shell Carbon, Gold Adsorption Carbon, CIP Carbon, CIL Carbon, Mining Activated Carbon
Product Overview
Gold Recovery Activated Carbon is produced from selected coconut shell feedstock and is widely used in gold extraction and precious metal recovery operations. The material is designed for adsorption of gold-cyanide complexes in Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), and Carbon-in-Column (CIC) processes.
The combination of a predominantly microporous structure, high mechanical strength, and low impurity content makes coconut shell activated carbon suitable for applications involving repeated adsorption, elution, regeneration, and handling cycles.
Product grades may be selected according to adsorption requirements, process conditions, and operating objectives.
Key Features
High Mechanical Strength
High hardness and abrasion resistance help reduce carbon loss during pumping, agitation, screening, and transfer operations commonly encountered in gold recovery circuits.
Pore Structure for Gold Adsorption
The pore distribution is suitable for adsorption of dissolved gold-cyanide complexes generated during cyanide leaching processes.
Low Ash Content
Controlled ash levels help minimize introduction of inorganic contaminants into downstream processing systems.
Regeneration Compatibility
The carbon is suitable for thermal regeneration processes used in many gold recovery operations, subject to process conditions and operating practices.
Consistent Particle Size Distribution
Uniform sizing supports screening efficiency, carbon handling, and hydraulic performance in adsorption circuits.

Carbon-in-Leach (CIL)
Applied directly within leaching circuits where gold dissolution and adsorption occur simultaneously.
Carbon-in-Column (CIC)
Suitable for fixed-bed or moving-bed adsorption columns treating pregnant leach solution (PLS) generated from heap leaching or other recovery processes.
Heap Leach Recovery Circuits
Used in downstream adsorption systems to recover dissolved precious metals from leachate streams.
Precious Metal Recovery
Can be utilized in selected recovery applications involving gold, silver, and other precious metal-bearing process solutions.

Operating cost objectives
A review of process conditions and recovery targets can help determine the most suitable activated carbon grade for a specific mining operation.
Common Gold Recovery Processes
Carbon-in-Pulp (CIP)
Leaching and adsorption occur in separate stages. Gold is first dissolved into solution and then adsorbed onto activated carbon.
Carbon-in-Leach (CIL)
Leaching and adsorption occur within the same tank system, reducing process stages and carbon transfer requirements.
Carbon-in-Column (CIC)
Pregnant leach solution is passed through adsorption columns containing activated carbon for recovery of dissolved precious metals.
The appropriate process configuration depends on ore characteristics, plant design, recovery objectives, and operating conditions.
