Slurry Filtering & Concentrate Filtration

The purpose of a vacuum filter is Slurry Filtering and therefore to remove more of the water from the concentrate, this Concentrate Filtration is accomplished by using a vacuum. Again for your understanding of the method you will have to know something about the design of a filtering system and of course the filter itself. There is always something being filtered in the mining ...

Coal washing process and slime dewatering, recycling | LZZG

The filter press, after pressure filtration, obtains flotation clean coal, which is transported by the belt to the clean coal yard together with the fine coal dewatering sieve and the coarse coal recovered by the high-frequency sieve. The filtrate did not circulate. The flotation tailings well enter the thickener for concentration of the slime.

Dewatering Equipment - 911Metallurgist

Concentrate Thickening & Filtration The concentrate (or concentrates) produced in the facility must usually be dewatered prior to shipment. The first step of the dewatering procedure is usually sedimentation. The design engineer must be extremely careful when developing the size of concentrate thickeners from laboratory data. In the laboratory, concentrates settle extremely rapidly. Calculated ...

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 disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing.
