For any gold mining operation that utilizes cyanide leaching, the selection of activated carbon is a decision with significant financial implications. The efficiency of gold recovery processes like CIP (Carbon-in-Pulp), CIL (Carbon-in-Leach), and CIC (Carbon-in-Column) is directly tied to the performance of the activated carbon used. As a dedicated manufacturer and supplier of specialized activated carbon, we aim to guide prospective buyers through the critical parameters to consider when making this vital purchase. Understanding these specifications ensures you invest in a product that maximizes your return on investment.

Key Specifications to Consider:

  1. Material Source: Coconut shell activated carbon is the industry standard for gold recovery due to its inherent hardness, microporous structure, and low ash content. While coal-based carbons can be used, they generally exhibit lower hardness and may not perform as efficiently.
  2. Particle Size: The ideal particle size balances adsorption rate with sieving efficiency. Commonly used sizes include 6x12 mesh, 8x16 mesh, and 6x16 mesh. Smaller particles adsorb faster but can be lost more easily during screening. Larger particles are easier to handle but adsorb more slowly. We offer a range of precisely screened sizes to suit various process requirements.
  3. Hardness and Abrasion Resistance: This is arguably one of the most critical specifications. Activated carbon is subjected to significant wear in mining circuits. A high hardness percentage (typically ≥ 98%) ensures minimal attrition loss, preserving both the carbon and the adsorbed gold. Our manufacturing process prioritizes creating extremely hard carbon particles.
  4. Adsorption Capacity (Iodine and CTC Values): The iodine value (mg/g) indicates the total pore volume and surface area, while the CTC value (%) reflects the capacity for adsorbing carbon tetrachloride, a measure of micropore volume relevant to gold adsorption. Higher values generally signify better performance. We consistently achieve high iodine and CTC values in our products.
  5. Moisture Content: Low moisture content (typically ≤ 5%) is important for handling and consistent performance.
  6. Ash Content: Low ash content ensures that impurities do not interfere with the adsorption process.
