May 21, 2019· 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.

An implementation of two-step concentration (afterpurification) allowed increasing the iron content in the concentrate up to 48.2%. It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase (so-called, wet separation). Fig. 5 shows the iron ore after the process of magnetic separation.
