Optimization of magnetic separation process for iron

Feb 01, 2017 To improve the efficiency of iron recovery from steel slag and reduce the wear-and-tear on facilities, a new method was proposed by adding a secondary screen sizer to the magnetic separation process according to grain size distribution of magnetic iron (M-Fe) in the slag. The final recycling efficiency was evaluated by calculating the percentage of recycled M-Fe to the maximum amount of

Maximizing the recovery of fine iron ore using magnetic

The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass.

Phosphate selective recovery by magnetic iron oxide

Feb 01, 2021 If a magnetic iron oxide such as magnetite (Fe 3 O 4) or maghemite (γ-Fe 2 O 3) is used, the iron oxide impregnated materials can be rapidly separated by application of an external magnetic field, thereby enabling the efficient recovery of the adsorbed P (Fang et al. 2017, Wu et al. 2017).

Magnetic Materials Saturation

Jun 09, 2008 The magnetic flux density, B, is the total magnetic effect that results in iron: B = u 0 * u r * H, where u 0 is the permeability of free space, and u r is the relative permeability of the material. The constant u r is essentially unity (= 1.0) for all materials except ferromagnetic materials, notably iron, for which the value of the relative
