It is known from the literature that magnetic particles with a diameter ≥ 0.5-1 μm can be easily separated by simple magnetic separators (e.g. a glass bottle without wire matrix and a permanent magnet as used in this work), while separation of smaller particles is much more efficient when high gradient magnetic separators are used (with internal wire matrix) [ 6, 43].
Several dry coal separation technologies, such as, All-Air® Jig (allmineral GmbH), Air Dense Medium Fluidizied Bed (ADFMB), Tirbo-electrostatic Separators, Rare Earth Magnetic Separators (REMS), and X-ray Sorting technologies, were proven effective in terms of separation to achieve low-ash products for coarse to mid-size fractions (Dwari and Rao 2008; Zhao et al. 2014).
This chapter presents the selection of magnetic separators to illustrate differences in approaches to magnetic cell separation.
With good results, strongly magnetic minerals such as magnetite, franklinite, and pyrrhotite can be removed from gangue minerals by low-intensity magnetic separators.
Because some nickel-bearing sulfides are magnetic, magnetic separators can be used in place of, or in conjunction with, flotation.
These materials had a profound effect on the design of many electrical devices, including magnetic separators, DC motors, and automobile generators.
This represents a powerful tool when designing magnetic separators.
None of the present magnetic separators is capable of achieving the classification of particles according to their magnetic susceptibility.
Reciprocating magnetic separators are used in waste water treatment for special steel factory.
The third category of magnetic separators generates the highest intensity magnetic field from 2 to 10 T (Selvaggi et al. 1998; Yan et al. 1996).
