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 from …

Magnetic separation: Separation generally adopts permanent magnet drum-type magnetic separator. Most magnetite beneficiation plants often adopt coarse-grained dry magnetic separation tailings. If ultra-lean magnetite ore is below 20%, the ultra-fine crushing-wet magnetic separation tailing process can be used before entering the mill.

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.
