The gold mining industry relies heavily on efficient and cost-effective methods for recovering gold from ore. Among the key consumables in this process, granular activated carbon plays a pivotal role, particularly in the carbon-in-pulp (CIP) and carbon-in-leach (CIL) circuits. As a seasoned manufacturer and supplier of activated carbon in China, we understand the stringent requirements of this sector and are dedicated to providing high-quality granular activated carbon that maximizes gold recovery and operational efficiency. This article explores the critical functions of our activated carbon in gold extraction and offers insights into sourcing and pricing.

The Crucial Role of Activated Carbon in Gold Recovery

In the cyanide leaching process, gold is dissolved from the ore into a cyanide solution. The activated carbon's role is to selectively adsorb the dissolved gold-cyanide complex (Au(CN)₂⁻) from this solution. The high surface area and specific pore structure of activated carbon, especially that derived from coconut shells, are ideal for this task. The carbon acts like a sponge, trapping the gold ions efficiently. Once the carbon is loaded with gold, it is separated from the pulp, and the gold is then stripped from the carbon using a hot, caustic cyanide solution, followed by electrowinning and smelting to produce doré bars.

Why Granular Activated Carbon? Properties for Optimal Performance

For gold extraction, granular activated carbon is the preferred form due to its ease of handling in slurry systems and its excellent mechanical strength, which resists attrition during the continuous circulation in CIP/CIL tanks. Key properties that make our activated carbon ideal for this application include:

  • High Iodine Value: Indicative of a high concentration of micropores, crucial for adsorbing the relatively small gold-cyanide complex.
  • High Hardness: Ensures minimal loss of carbon fines during processing, leading to better economic efficiency.
  • Low Ash Content: Minimizes interference with the leaching and stripping processes.
  • Consistent Particle Size: Facilitates efficient screening and handling within the circuits.

Our coconut shell activated carbon is specifically engineered to deliver superior performance in gold adsorption, offering an optimal balance of these critical characteristics.
