CIL (Carbon in Leach) is a widely used method for extracting gold from ore. It is a metallurgical process that involves the dissolution of gold particles into a cyanide solution and their subsequent adsorption onto activated carbon. Mining operations commonly employ this process to recover gold from low-grade or refractory ore. CIL Principle

CIL Carbon In Leach, the gold carbon leaching method, is the carbon leaching method for gold extraction. Normally, the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t in carbon. The CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content; Or process the gold tailings after ...
