We select coconut shells from Southeast Asia as raw material. After carbonization and high-temperature activation, the products have a large specific surface area, well-developed pore structure, excellent adsorption properties, high capacity, and easy desorption. Special technology is used to reshape and grind the activated carbon particles intensely, removing the parts prone to wear, enhancing the product's wear resistance, and ensuring uniform and full particle size. These particles require no further grinding upon arrival and can be directly used after water washing. They are suitable for the gold extraction process, including the carbon-in-pulp (CIP) method and heap leaching method.
