2002-6-1 The bigger the flocs, the higher is the separation efficiency. This suggests that the high efficiency of the FMS process might be due to the considerable increase of magnetic force on hematite fines in a magnetic field because of the formation of hydrophobic flocs, leading the fines to be held on the separation plates in a magnetic separator.

By applying the process to the fine hematite ore containing 30.5% Fe, a concentrate assaying 64% Fe with 82% recovery has been produced. It has been found that the separation efficiency of the FMS process closely correlates with the main parameters of hydrophobic flocculation such as sodium oleate addition, conditioning time and kerosene addition.

2021-11-9 Hematite. Hematite is an iron ore that contains iron in the form of Fe 2 O 3. It is a significant source of iron extraction. Hematite is a mineral that is paramagnetic. As a result, it can be drawn to an external magnetic field. Hematite is abundant in rocks and soil. Hematite’s magnetic properties are caused by unpaired electrons.

2010-7-16 When heated enough, hematite becomes a paramagnet, in which the atomic magnets just randomly point all different directions. Anyway, although hematite is weakly magnetic (and hence can be attracted to your magnet), its magnetism is "soft", meaning that its domains don't stay lined up when the magnetic field is removed.
