The quest for gold has always driven innovation in mining and metallurgy. Central to many modern gold extraction techniques, particularly those involving cyanide leaching, is the crucial role of activated carbon. For procurement managers and R&D scientists in the mining sector, understanding the specific properties of activated carbon, especially its iodine value, is paramount for optimizing recovery rates and ensuring cost-effectiveness. As a leading manufacturer and supplier, we provide insights into why high-iodine value coconut shell activated carbon is indispensable for this critical process.

Gold cyanidation, a widely adopted method for extracting gold from ore, relies on dissolved cyanide to leach gold into a solution, forming a gold-cyanide complex. The efficiency of recovering this dissolved gold hinges on a powerful adsorbent, and that’s where activated carbon shines. Specifically, coconut shell activated carbon, when processed to achieve a high iodine adsorption value, exhibits superior performance in adsorbing these gold complexes from the pregnant leaching solution. This makes it a preferred choice for operations like Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP), and Carbon-in-Column (CIC) systems.

Why High Iodine Value Matters for Gold Extraction

The iodine adsorption value (often measured in mg/g) is a key indicator of the amount of micropores within the activated carbon. A higher iodine value signifies a greater capacity to adsorb smaller molecules, which is crucial for capturing the gold-cyanide complexes effectively. For mining operations looking to purchase activated carbon, selecting a product with a high iodine value ensures maximum gold loading onto the carbon, thereby increasing the overall yield and economic viability of the extraction process. This characteristic, coupled with excellent mechanical strength and a well-developed pore structure, minimizes carbon loss during handling and elution, offering a reliable and reusable solution.
