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.

K = F /C = (c — t)/ (ft) = the concentration ratio. At operating plants, it is usually simpler to report the K based on assays. If more than one mineral or metal is recovered in a bulk concentrate, each will have its own K with the one regarded as most important being reported as the plant criteria.
