Gold Recovery with Activated Carbon

Activated carbon plays a crucial role in gold recovery processes due to its exceptional adsorption properties. Its highly porous structure and large surface area enable the efficient extraction of gold from cyanide leach solutions, making it indispensable in modern gold mining and refining.

Activated carbon, also known as activated charcoal, is a vital component in the gold recovery industry. It effectively adsorbs gold cyanide complexes from leach solutions, ensuring high recovery rates. Activated carbon is widely used in Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), and Carbon-in-Column (CIC) processes to optimize gold extraction efficiency.

Applications:

Gold Cyanidation Process

Carbon-in-Pulp (CIP): Activated carbon is introduced into the leach pulp to adsorb dissolved gold from the solution.

Carbon-in-Leach (CIL): Gold is leached and adsorbed simultaneously in a single tank, improving efficiency.

Carbon-in-Column (CIC): Used primarily in heap leaching operations where gold-laden solutions pass through carbon columns for adsorption.

Gold Adsorption & Recovery: Activated carbon effectively captures gold cyanide complexes, ensuring high yield and recovery rates.

Efficient Adsorption: Rapidly absorbs gold from cyanide solutions, minimizing gold loss.

Regeneration & Reusability: Carbon can be thermally regenerated, maintaining performance over multiple cycles.

Gold Refining & Smelting: After adsorption, gold-laden carbon undergoes elution, where gold is desorbed and recovered through electrowinning or precipitation, followed by smelting to obtain pure gold.
