Para-magnetic minerals like hematite, goethite, ilmenite, garnet, etc. behave as magnetic minerals whereas the associated minerals behave as non-magnetic minerals when a high intensity magnetic field is applied. The magnetic separators are designed on the basis of magnetic field intensity and are available in permanent and electro-magnetic types.
In ilmenite plants, the raw ore is classified into coarse (+20 μm) and fine (−20 μm) fractions. The coarse ore can be effectively preconcentrated using conventional magnetic separators [1, 12, 13], and currently, SLon magnetic separator is being applied well in plants [14].However studies on fine ore are still being conducted in the start-up stages.

As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at a distance of 50 mm …
These work well in removing ferrous tramp but not fine para-magnetic particles. High intensity magnetic separators focus on the separation of very fine particles that are para-magnetic. Controlled current is passed through an electromagnetic coil, which creates a magnetic field. This magnetises the yoke and finally the matrix ring.

The MAGQUIP Wet High Intensity Magnetic Separator (WHIMS) is a high gradient magnet used for the concentration of slurries containing weakly magnetic minerals. The magnetic separation of paramagnetic minerals demands a high magnetic field gradient as well as a high magnetic flux density. For wet magnetic separation the best arrangement is a closely pitched matrix
