Gold Recovery Process (CIL / CIP / HL)
Activated carbon, a highly porous material with a vast surface area, has been widely used in the gold recovery process for decades. Its ability to adsorb gold from cyanide solutions has made it an indispensable tool in the mining industry. Two primary methods of using activated carbon in gold recovery are Carbon in Leach (CIL) and Carbon in Pulp (CIP).
CIL / CIP
In the Gold recovery process, activated carbon is added directly to the gold-bearing cyanide tanks. The cyanide dissolves the gold from the ore which is then adsorbed by the activated carbon. The loaded carbon is then separated from the solution and subjected to a desorption process to recover the gold.
Advantages of Activated Carbon in Gold Recovery
- High Gold Recovery Efficiency: Activated carbon can achieve high gold recovery rates, even from low-grade ores.
- Selectivity for Gold: Activated carbon is selective for the gold cyanide complex.
- Versatility: Both CIL and CIP processes can be adapted to various ore types and operating conditions.
Activated carbon is a valuable tool in the gold recovery process, offering high efficiency, selectivity, and versatility. By understanding the factors that influence gold adsorption and desorption, it is possible to optimize the use of activated carbon in CIL and CIP processes, maximizing gold recovery and minimizing environmental impact.
