Laboratory Hematite Magnetic Separation Testing
Hematite is a weakly magnetic mineral with a specific magnetic susceptibility ranging from 3.8×10-5m³/kg to 1.26×10-7m³/kg. Its magnetic characteristic is that the relationship between the magnetization intensity and the external magnetic field intensity is a straight line, without the hysteresis or magnetic saturation phenomenon that vital magnetic minerals have.

Magnetic separation of hematite and limonite fines as hydrophobic flocs
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.
