The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again, the addition of polymer aids in the separation and thickening process.

The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...

• 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.

t. e. In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

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.

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.
