Efficient Gold Recovery: Adsorption of Gold by Activated Carbon in Leaching

Adsorption of Gold by Activated Carbon in Gold Leaching 

Activated carbon has become one of the most important materials in modern gold metallurgy. In the gold leaching process, especially in Carbon-in-Leach (CIL) and Carbon-in-Pulp (CIP) technologies, activated carbon is used to selectively adsorb gold cyanide complexes from the slurry. This step is essential for improving recovery efficiency and ensuring high yields.

Boyue Carbon, as a professional manufacturer of activated carbon, provides premium coconut shell-based activated carbon and coal-based columnar activated carbon, both widely recognized for their efficiency in gold recovery applications. With large surface area, highly developed pore structure, and strong mechanical strength, Boyue Carbon’s products are designed to maximize gold loading capacity while extending service life.

The adsorption mechanism involves three key aspects:

1. Physical adsorption – The microporous structure of activated carbon provides abundant sites for gold cyanide complexes.

2. Chemical interaction – Oxygen-containing functional groups on the carbon surface enhance retention of gold complexes.

3. Ion exchange – Under certain conditions, selective ion exchange improves the overall gold recovery rate.

As global demand for gold continues to rise, efficient and durable activated carbon is playing an increasingly important role in the mining industry. Boyue Carbon is committed to delivering reliable, cost-effective activated carbon solutions that support sustainable and efficient gold recovery worldwide.
