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. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 µm, by using WHIMS2.

After magnetic separation, the magnetic concentrates consisted almost completely of magnetite (with the magnetization of 75–88 Am2/kg) and non-magnetic residues contained major quartz. The content of iron in magnetic concentrates reached 68.5–70.2 wt.% and iron recovery 77–96 wt.%, depending on size fraction.

Magnetite is magnetic, so we can use the magnetic beneficiation method to purify it. Magnetic beneficiation, referred to as magnetic separation, is a method of beneficiation using the difference in magnetic conductivity between minerals, and it occupies an extremely important position in the field of iron ore beneficiation.

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
