Magnetic Separation

Magnetic Separation It is a process in which magnetically susceptible material is extracted from a mixture using a magnetic force. Since 19th century magnetic separation processes have been used to concentrate and separate minerals. Magnetic separation takes advantage of differences in the magnetic properties of minerals.

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 Ferromagnetism/ ferromagnetic (materials strongly affected by magnetic

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

magnetic separation early in a process can greatly benefit an operation if a low-grade final tailing, or a clean marketable product, can be produced, since it alleviates both drying and dry storage costs. While WHIMS use can be advantageous, a common drawback of conventional designs is entrapment of non-

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,

Magnet - Wikipedia

A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, and the magnitude relates to how strong and how far apart these poles are. In SI units, the magnetic
