Magnetic Separation and Iron Ore Beneficiation – IspatGuru

Oct 04, 2018  Also, the magnetic force in a separator can be maximized by matching the magnetic field gradient to the particle size. Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings.
