The removal of iron as magnetite from a high iron bauxite ore was investigated by carbothermal reduction and magnetic separation. Thermodynamic calculations using HSC Chemistry 6·1 were utilised to determine the equilibrium compositions of the reaction products as a function of temperature and carbon additions.
Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will ...
WHIM is the short acronym for Wet High Intensity Magnetic Separation.

After 20 years practice, Xinhai Magnetite Separation Production Line reduces the production line cost by improving separation equipment. ... Serial grinding – weak magnetic separation is suitable for magnetite with large disseminated grain size or high iron grade. It can be divided into one stage grinding and serial two serial stage grinding.
Eriez is world authority in magnetic separation technologies. Since 1942, Eriez provides a range of permanent and electromagnetic separators for many industries.
Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can …
Magnetic separations at very low magnetic field gradients (<100 tesla per meter) can now be applied to diverse problems, such as point-of-use water purification and the simultaneous separation of complex mixtures. High-surface area and monodisperse magnetite (Fe3O4) nanocrystals (NCs) were shown to respond to low fields in a size-dependent fashion.
Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a common magnet. It is a black, opaque, submetallic to metallic mineral with a Mohs hardness between 5 and 6.5. It is often found in the form of isometric crystals. It is the most strongly magnetic mineral ...

Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite, however, in contrast to hexagonal pyrrhotite, is magnetic and is recovered in magnetic concentrates.
The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic separation.

Oct 04, 2018· Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
[Process Description] Strong magnetic iron ore separation process. It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding.
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.
