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.

• Within the scope of a dewatering circuit are three categories of equipment. THICKENERS, FILTERS and the DRIERS. Each one is a stage in producing a dry final product. One of the good things about milling is that the names of most of the equipment reflect what function they perform. With thickener's they thicken! The feed to them has low density.

The thickener is 150 m diameter and was designed to process 13000 m3/h of pulp, containing 27% of solids, with a specific gravity of, to deliver an underflow with a 54% of solids. The flocculants is added at a rate of 15g/ton of pulp or about 270 m3/h of a solution with a low flocculants concentration (%).

The core of thickening process control is to adjust the underflow ore drawing speed in time according to different working conditions. When flocculant is added, it is necessary to adjust the amount of flocculant in time to obtain the best sedimentation velocity, so that the underflow ore discharging speed and ore discharging concentration are in the best matching interval.
