Jun 01, 2002· 1. Introduction. In a magnetic separation system, the force on a particle toward increasing field intensity (F) is expressed by (Svoboda, 1987) (1) F∝V(S p −S o)H d H d l, where V is the volume of the particle; S p and S o are the magnetic susceptibility of the particle and surrounding media, respectively; H is the magnetic field intensity; and dH/dl is the magnetic field gradient.

Difference Between Magnetite and Hematite Definition

Jan 31, 2018· Hematite has unpaired electrons that cause its magnetic properties. It is paramagnetic because it has only ferric ion (Fe 3+).The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore, hematite can be separated from a mixture using high-intensity magnetic separation methods which use magnetic fields with intensity ranging from

Magnetic separation Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are

Magnetic Separation an overview ScienceDirect Topics

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.
