Wet Magnetic Separator. The use of wet magnetic separator: Wet magnetic separator is widely used in beneficiation, coal washing and chemical departments for wet sorting particle size 60 mm strong magnetic minerals, and the mineral is divided into two products of the magnetic material and nonmagnetic material.

Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from runofmine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.

Compared to conventional cylinder and dry magnetic separator, this patented product solves the eddy current heating problem, ore sticking problem for separation cylinder, and mine unloading problem of conventional 360 degree rotating magnetic dry separator.

The inclusion of medium intensity magnetic drum separation (MIMS) in combination with jigging may be considered for the beneficiation of the 61mm fraction of some friable ore bodies. The following diagram demonstrates some typical flowsheet designs for Iron Ore beneficiation of hard rock and friable ores.

Magnetic system is compounded of ferrite and permanent magnets; the average magnetic induction intensity of cylinder surface is 100～600mT. The same cylinder can be equipped with three types of tank adapting to different dressing process. Small area taken, good separation for magnetic mineral, reduce the load of next process.
