Magnetic Separation an overview ScienceDirect Topics

Magnetic separation: based on the generation of magnetic forces on the particles to be separated, which are higher than opposing forces such as gravity or centrifugal forces. This principle is used to separate ferromagnetic particles from crushed scrap mixtures. • Eddy current separation: is a particular form of magnetic separation. An

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 who 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 less

Joan S. Esterle, in Applied Coal Petrology, 2008. 3.7.5 Magnetic Separation. High gradient magnetic separation (HGMS) (Trindale et al., 1974, and Liu, 1982) is based on coal being diamagnetic (repulsed by a magnet), whereas pyrite is paramagnetic (attracted to a magnet). The magnetic susceptibility of pyrite is 0.3 × 10-6 G/g (G = gauss), compared to coal at -0.4 × 10-6 to –0.8 × 10-4 G/g.

Magnetic Seperation

The device used to separate minerals based on their magnetic properties is called a Frantz Isodynamic Magnetic Separator. The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field and/or slope of the separation trough is used to separate minerals.

Magnetism Wikipedia

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.The most familiar effects occur in ferromagnetic materials, which are strongly
