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.

More than 90% of the global iron ore production is beneficiated by the magnetic separation process because the dominant iron ore minerals are para- and ferromagnetic . Magnetite is the principal ferromagnetic mineral that is concentrated through low-intensity magnetic separators (<~0.3 T) because of its strong magnetic response [ 121 ].
