In the world of mining and refining, the efficient recovery of precious metals like gold is a critical economic driver. NINGBO INNO PHARMCHEM CO.,LTD. offers specialized coconut shell activated carbon that plays a pivotal role in these demanding applications. The unique characteristics of this material, particularly its high hardness, superior pore structure, and excellent adsorption capacity, make it a preferred choice for processes such as gold recovery from leach solutions.

The primary method for extracting gold from ore involves leaching, typically using cyanide solutions, which dissolves the gold into an aqueous solution. The challenge then becomes recovering the dissolved gold efficiently from this complex mixture. This is where activated carbon excels. Coconut shell activated carbon, in particular, is highly valued for its ability to selectively adsorb gold cyanide complexes from the leach liquor. Its microporous structure is ideally suited for capturing these specific molecular species, while its high surface area ensures a significant loading capacity for the gold.

A key advantage of coconut shell activated carbon in precious metal recovery is its exceptional physical hardness and resistance to attrition. In gold recovery processes, the activated carbon is often subjected to continuous circulation, backwashing, and thermal regeneration. Materials that are less durable can break down, creating fines that are lost during these operations, leading to reduced recovery efficiency and increased operational costs. The superior abrasion resistance of coconut shell carbon ensures it maintains its integrity and adsorptive capacity throughout multiple cycles, making it a cost-effective and reliable solution for mining operations.

The process of using activated carbon for gold recovery typically involves either the carbon-in-pulp (CIP) or carbon-in-leach (CIL) methods. In these methods, the activated carbon is introduced directly into the ore slurry or leach tanks, where it adsorbs the gold as it is leached from the ore. Once the carbon is loaded with gold, it is screened from the slurry and then processed to recover the gold, often through elution (stripping the gold from the carbon) followed by electrowinning or smelting. The activated carbon can then be reactivated and reused, further enhancing the economic and environmental sustainability of the process.

Beyond gold, coconut shell activated carbon can also be utilized for the recovery of other precious metals, such as platinum and palladium, from various industrial streams. Its high chemical stability ensures it performs effectively in the often challenging chemical environments associated with metal refining.
