On the contrary, hematite (α-Fe 2 O 3) is a weakly magnetic mineral and is hardly attracted by a magnetic field. Hematite quartzite deposits are often associated with magnetite quartzite. Therefore, hematite and quartz particles accumulate during exploitation and beneficiation of magnetite ore, thus forming tailings and other industrial waste.
