Our high-quality coconut shell activated carbon plays a critical role in the gold extraction process by ensuring maximum metal recovery and minimizing losses due to carbon degradation. We focus on reducing carbon attrition and fine formation, which helps maintain operational efficiency and recovery rates.
Product Applications
Gold Recovery in Mining
Activated carbon is a key material in the gold extraction industry. During the process, even just a few grams of gold require the mining, crushing, grinding, and leaching of thousands of tons of ore. Our coconut shell GAC is designed for use in:
-
CIP (Carbon-in-Pulp): Gold is first leached from the ore into slurry, then adsorbed by carbon added into multiple stirred tanks. Loaded carbon is later separated for recovery.
-
CIL (Carbon-in-Leach): Leaching and adsorption occur simultaneously in this process, developed to counteract natural carbonaceous materials that compete for gold adsorption.
-
CIC (Carbon-in-Column): Used mainly after heap leaching, where solutions—not slurry—are processed through carbon columns.
A major concern in all these systems is carbon wear and the formation of fine particles. These fines can continue to adsorb gold but are often lost during screening, leading to unrecoverable precious metals. Our products address this by offering:
-
High hardness and durability
-
Low attrition rate to minimize carbon loss
-
Maximum gold loading and adsorption efficiency
Backed by decades of experience, Jiayuan, Yulong, and Longkai have been trusted suppliers of high-performance activated carbon to gold mines worldwide, delivering reliable quality and outstanding technical support.
