    Carbon in 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 preg robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

    Alkaline cyanide leaching of refractory gold flotation

    Since gold leaching is an oxidative process, higher pulp oxidation potential will improve the leaching rates based on the potential gradient between the leaching species and the bulk pulp (Puddephatt, 1978). Consequently, the higher pulp redox potentials of the quicklime modified pulps were expected to increase the leaching rate for the initial
