> Coconut shell activated carbon is critical consumable media for gold CIL (Carbon in Leach) and CIP (Carbon in Pulp) gold extraction circuits. It adsorbs dissolved gold cyanide complex from ore slurry. High mechanical hardness minimizes carbon fines and gold loss. Widely used in gold mineral processing plants for gold recovery. Custom specifications available.
Activated Carbon for CIL & CIP Gold Processing
High Hardness Coconut Shell Activated Carbon for Gold Recovery Plant
Product Overview
Coconut shell activated carbon is a professional adsorption medium specially developed for gold mineral processing, widely used in CIL (Carbon in Leach) and CIP (Carbon in Pulp) gold extraction processes. Different from ordinary water purification carbon, gold-grade activated carbon features ultra-high mechanical hardness, strong abrasion resistance and developed micropore structure, which can efficiently adsorb dissolved gold cyanide complexes from ore slurry.
In gold processing plants, activated carbon continuously captures fine gold ions in cyanide leaching slurry. After adsorption, gold-loaded carbon goes through desorption, electrolysis and smelting to complete gold recovery. It is the core consumable for modern low-grade gold ore beneficiation production lines.
Disclaimer: All products are professional industrial consumables for mineral processing, customized for gold CIL/CIP working conditions.
CIL & CIP Working Principle
- CIP (Carbon in Pulp): Ore slurry is leached and cyanided first to dissolve gold. Activated carbon is then added into the slurry tank to adsorb free gold cyanide complexes separately.
- CIL (Carbon in Leach): Leaching reaction and carbon adsorption are carried out simultaneously in the same tank. While gold is dissolved, activated carbon immediately captures gold ions, improving processing efficiency and saving plant space.
- Core Adsorption Function: The rich microporous structure of coconut shell carbon selectively adsorbs dissolved gold from slurry, realizing solid-liquid separation of gold and ore slurry.
- Recyclable Use: After desorption and regeneration treatment, activated carbon can be recycled repeatedly, reducing production cost for mineral plants.

FAQ
Q: Why use coconut shell carbon for gold CIL/CIP instead of ordinary carbon?
A: Coconut shell activated carbon has higher hardness and wear resistance, not easy to produce powder in stirred slurry. It avoids gold loss caused by fine carbon leakage and has higher gold adsorption efficiency, which is specially adapted for gold mineral processing.
Q: What is the difference between CIL and CIP process?
A: CIP separates leaching and carbon adsorption, while CIL completes leaching and adsorption synchronously in one tank. CIL is more efficient and saves investment, which is the mainstream process for modern large-scale gold mines.
Q: Can activated carbon be reused in gold processing?
A: Yes. After desorption, electrolysis and regeneration treatment, the activated carbon can restore adsorption performance and be recycled for multiple times.
Q: How to choose the right particle size?
A: 6×12 mesh is suitable for conventional CIL/CIP production lines; 8×16 mesh is for fine slurry and high-precision gold recovery scenarios. We can recommend the best specification according to your site conditions.
