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.
In Australia, a wide variety of techniques are used to process gold ore. At most facilities, a key step is the extraction of gold from the crushed ore using cyanide and carbon adsorption. This can be done using carbon in pulp (CIP) and carbon in leach (CIL) processes where the gold-cyanide complex binds preferentially to activated carbon.
between CIL and CIP.) The CIL process requires a larger carbon inventory in the circuit, which results in a larger in-process tie up of gold. The larger carbon inventory can also result in higher carbon (and gold) losses through carbon attrition. CONCLUSION. Denver Mineral Engineers has had extensive experience with all of the
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using ﬂotation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density.
