Gold Recovery Activated Carbon for CIP, CIL and CIC

PSD-GOLD is a high-hardness coconut shell granular activated carbon developed for gold recovery circuits using carbon-in-pulp (CIP), carbon-in-leach (CIL) and carbon-in-column (CIC) processes. Its strong granular structure helps the carbon withstand repeated pumping, screening, elution and regeneration operations in demanding mining environments.

With a minimum hardness of 98%, iodine number of at least 1050 mg/g and controlled particle-size options, PSD-GOLD is designed for mining operations requiring stable adsorption performance, low carbon attrition and reliable handling throughout the recovery circuit. For a broader overview of activated carbon selection in mining, see our activated carbon solutions for gold extraction.

Why PSD-GOLD for Gold Recovery?

Gold recovery carbon must combine adsorption performance with the mechanical strength required to survive repeated circulation through the plant.

01

High Mechanical Strength

A minimum hardness of 98% helps reduce particle breakdown during pumping, screening, carbon transfer and repeated handling throughout the adsorption circuit.

02

Microporous Coconut Shell Structure

The pore structure of coconut shell activated carbon is well suited to the adsorption of dissolved gold complexes from cyanide leach solutions, supporting efficient contact between the carbon and gold-bearing liquor.

03

Controlled Particle Size

PSD-GOLD is available in particle sizes suitable for different recovery configurations, allowing operators to balance adsorption, hydraulic behavior and carbon retention requirements.

04

Suitable for Regeneration Circuits

Strong granular integrity supports repeated handling through elution and thermal regeneration processes when operated under appropriate plant conditions.

Typical Gold Recovery Applications

CIP – Carbon in Pulp

Used to adsorb dissolved gold from cyanide leach slurry after the primary leaching stage. High carbon hardness is important where particles undergo repeated agitation, transfer and screening.

CIL – Carbon in Leach

Applied directly in the leaching circuit so that leaching and adsorption occur within the same process train, requiring carbon with consistent particle integrity and adsorption performance.

CIC – Carbon in Column

Suitable for column-based adsorption of gold-bearing clarified solutions, including applications associated with heap-leach recovery systems.

Product Selection

What Information Helps Us Recommend the Right Grade?

Activated carbon performance depends on more than iodine number alone. When evaluating carbon for a CIP, CIL or CIC circuit, it is useful to provide the operating conditions and specifications of the plant.

  • Gold recovery process: CIP, CIL or CIC
  • Required particle size or interstage screen specification
  • Target iodine number or CTC activity
  • Required hardness and ash limits
  • Current activated carbon grade, if available
  • Estimated trial quantity or annual consumption
  • Destination country and preferred packaging

If you are comparing several grades of granular activated carbon, our team can review your existing specification and help identify an appropriate product for further testing.

Manufacturing & Batch Verification

Consistency between activated carbon batches is important in gold recovery plants because changes in particle strength, activity or particle-size distribution can affect plant operation. PSD-GOLD is manufactured with control over raw-material selection, activation, sizing and finished-product inspection.

Product batches are checked against defined quality parameters such as iodine number, hardness, ash, moisture and particle size before shipment. Relevant product documentation can be supplied according to order and project requirements.

Gold Recovery Activated Carbon FAQ

What particle size is commonly used for CIP and CIL?

6×12 mesh is a commonly used particle-size range for many CIP and CIL applications. However, the appropriate size should be selected according to interstage screen openings, hydraulic conditions, carbon-retention requirements and individual plant design.

Why is hardness important for gold recovery activated carbon?

Activated carbon is repeatedly pumped, screened and transferred through the recovery circuit. Higher mechanical strength helps reduce particle breakdown and fines generation during these operations, supporting more stable carbon handling.

Can PSD-GOLD be used in thermal regeneration circuits?

PSD-GOLD is designed for gold recovery systems that use elution and thermal regeneration. Actual regenerated-carbon performance depends on operating conditions, fouling, stripping procedures and regeneration parameters.

Can you provide a COA, TDS or sample?

Product documentation can be provided according to the grade and project requirements. For sample evaluation, send us your required particle size, target specification, application and estimated purchase quantity so that availability can be confirmed.

  • Q
    What specific properties make PSD-GOLD ideal for gold recovery operations?
    A

    PSD-GOLD is manufactured from dense, mature coconut shells with high lignin content, delivering a robust granular structure for CIP, CIL, and CIC circuits. Its micropore architecture is tuned for rapid aurocyanide complex adsorption, while >98% hardness—the highest in the coconut shell range—minimizes fines generation during interstage screening. The result is high gold loading capacity, low attrition, and consistent performance in abrasive slurry environments.

  • Q
    How does PSD-GOLD minimize gold losses in recovery circuits?
    A

    Softer carbons generate excessive fines during pumping and screening; these fines escape interstage screens and carry adsorbed gold into tailings. PSD-GOLD’s >98% hardness resists mechanical breakdown under continuous slurry abrasion, drastically reducing fines generation. Less carbon loss means fewer gold particles reporting to tailings and lower carbon makeup costs.

  • Q
    What is the regenerability of PSD-GOLD after gold stripping?
    A

    PSD-GOLD supports efficient thermal reactivation. Its stable pore structure restores adsorption capacity across multiple regeneration cycles with minimal structural degradation. This multi-cycle regenerability reduces fresh carbon consumption and lowers operating costs in high-volume gold processing plants.

  • Q
    What mesh size is best for CIP/CIL/CIC gold recovery operations?
    A

    PSD-GOLD is available in 6×12 mesh and 4×8 mesh. The 6×12 mesh suits most CIP and CIL operations, balancing adsorption kinetics with screen separation efficiency. The 4×8 mesh is preferred for CIC systems where larger particles support solution flow dynamics. Both sizes maintain the same high hardness and gold-loading performance.

  • Q
    Why choose coconut shell carbon over wood or peat carbon for gold mining?
    A

    Wood and peat carbons suffer from significantly higher attrition in abrasive CIP/CIL slurries, generating fines that carry gold into tailings and inflate carbon losses. PSD-GOLD selects premium coconut shells with high lignin content and engineers the micropore structure specifically for aurocyanide adsorption, delivering the mining-grade hardness and recovery efficiency that softer carbons cannot match.
