Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
The magnetic separation may have a beneficial effect in extracting the potentially marketable iron ore, which may bring the economic benefits by saving the energy required for separating the iron ore from the mineral mixture (O'Connor et al., 2001). It is also reported that in the case where magnetic separation and thermal treatment both are ...
