Activated Carbon for Gold Recovery in Mining(CIP,CIL,CIC)
Engineered for High Yield & Low Loss in Precious Metal Extraction. Xingsen's coconut shell activated carbon is specifically processed to maximize gold adsorption kinetics while minimizing fines generation. Trusted by gold processing plants globally, our carbon delivers consistent K/R performance under the harshest leaching conditions. From heap leaching to high-pressure CIP circuits, we ensure you extract every possible ounce.

Gold recovery efficiency is determined not only by the leaching process but also by the performance of activated carbon.

In CIP, CIL, and CIC systems, low-quality carbon can lead to:

  • High gold loss
  • Excessive carbon attrition
  • Increased operating costs

To address these issues, coconut shell activated carbon is widely used in gold recovery due to its high hardness and well-developed micropore structure.

Our coconut shell activated carbon is specifically designed for gold recovery applications, offering high hardness, optimized pore structure, and stable adsorption performance.

How Activated Carbon Works in Gold Recovery

Activated carbon is used to adsorb gold-cyanide complexes from leach solutions.

In industrial mining, three main processes are used:

  • CIP (Carbon in Pulp)
  • CIL (Carbon in Leach)
  • CIC (Carbon in Column)

The adsorption efficiency depends on:

  • Surface area and pore structure
  • Particle size distribution
  • Mechanical strength

XingSen Coconut Shell Activated Carbons For Gold Refining

Carbon-In-Column(CIC)
🔹 Process Description: The CIC (Carbon-in-Column) process is utilized within heap leaching systems, where gold-bearing solutions are passed through activated carbon columns for adsorption and recovery.

Applicable Products: 6×12 / 12×30 Mesh (Custom particle sizes available upon request)

Key Pain Point: Uneven flow rates can easily lead to "channeling"—the formation of preferential flow paths—thereby reducing adsorption efficiency.

Solution: By employing a design featuring uniform particle size and a high-strength structural matrix, the solution ensures uniform flow distribution, effectively preventing channeling issues and boosting overall adsorption efficiency by approximately 15–20%.
Carbon-In-Pulp(CIP)
🔹 Process Description: The CIP process involves adding activated carbon to the mineral pulp—following the completion of leaching—to adsorb gold complexes.

Applicable Products: 6×12 Mesh, High-Strength, Abrasion-Resistant Coconut Shell Activated Carbon

Key Pain Points: The intense agitation involved in the process causes carbon particles to fracture easily, leading to increased carbon loss and posing a risk of gold loss.

Solution: Utilizing high-hardness activated carbon (≥98%) effectively minimizes the generation of fines, maintains stable adsorption performance, thereby reducing carbon loss and enhancing the overall recovery rate.
Carbon-In-Leach(CIL)
🔹 Process Description: The CIL (Carbon-in-Leach) process involves the direct addition of activated carbon during the leaching stage, thereby enabling the simultaneous occurrence of leaching and adsorption.

Applicable Products: 6×12 / 8×16 Mesh, High-Activity Coconut Shell Activated Carbon

Key Challenges: The process environment is complex, imposing stringent requirements on adsorption kinetics, stability, and resistance to interference.

Solution: Through a design featuring a high iodine value (≥1000 mg/g) and a well-developed microporous structure, the activated carbon retains its rapid adsorption capability even within the mineral slurry, thereby enhancing the adsorption efficiency of gold complexes and ultimately boosting recovery rates.

Key Specifications for Gold Recovery Carbon

Choosing the right carbon is critical. Below are the key parameters:

Parameter Value
Particle Size 6×12 / 8×16 mesh
Iodine Value ≥ 900 mg/g
Hardness ≥ 97%
Ash Content ≤ 3%
Moisture ≤ 5%

High hardness = less carbon loss
Proper size = better adsorption + easier separation

Why Coconut Shell Activated Carbon is Preferred

Compared with coal-based carbon, coconut shell carbon offers:

  • Higher hardness → lower attrition loss
  • More micropores → better gold adsorption
  • Longer service life → reduced replacement cost

This makes it the preferred choice in most gold mining operations.

How to Choose the Right Activated Carbon

When selecting carbon for gold recovery, consider:

  • Process type (CIP / CIL / CIC)
  • Required particle size
  • Hardness and attrition resistance
  • Adsorption capacity

If you’re unsure, our technical team can recommend the best solution based on your system.

FAQ
