### Magnetic Separation and Iron Ore Beneficiation IspatGuru

Oct 04, 2018· The trapped magnetic particles are easily washed out when the applied field is reduced to zero. Magnetic separators of this type are useful for the concentration or removal of fine magnetic particles when processing of iron ore for pellet feed. Magnetic separators are integral part of the low grade iron ore beneficiation systems.
