Carbonin leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

The addition of 5 wt% activated carbon has less endothermic peak (379 °C) than that of ZK60 with 5 wt% copper, which has an endothermic peak of 405 °C. The microstructural observations indicate that ball milling has reduced the grain size to 22 nm after 20hr of milling time. The addition of copper has produced new phases (CuMg2 and CuMgZn).
