Activated carbon for gold recovery
Activated carbon plays a key role in the gold refining process. Its ultra-high porosity structure makes it a powerful adsorbent for gold recovery from cyanide solutions. After the metal ore is ground, it reacts with the cyanide solution to form a gold cyanide complex, and then the gold is adsorbed through activated carbon and recovered. Characteristics of activated carbon such as adsorption capacity, adsorption rate and particle size distribution are critical to gold recovery. As the most commonly used type, coconut shell activated carbon is ideal for gold extraction due to its superior hardness and pore structure.
