magnetic separation increase

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.

Principles of Magnetic Separation - Minerallurgy

Magnetic separation may be used for coal beneficiation when the gangue minerals contain such iron phases, however their very weak magnetic susceptibilities would require strong magnetic field strength (Dwari and Rao, 2009). Previous works on the magnetic separation of pyrite from coal have shown pyrite to be a weakly paramagnetic mineral.

Self-inductance, the effect of Faraday’s law of induction of a device on itself, also exists. When, for example, current through a coil is increased, the magnetic field and flux also increase, inducing a counter emf, as required by Lenz’s law. Conversely, if the current is decreased, an emf is induced that opposes the decrease.

Principles of Magnetic Separation - Minerallurgy

Based on the difference in the mechanism by which magnet magnetic fields are generated, the efficiencies of separation also differ. One way to measure the efficiency is through the determination of grade quality and the quantity equated to recovery, achieved under the different techniques (Oberteuffer, 1974; Chakravorty, 1989).

Danish scientist Hans Christian Ørsted discovered in 1820 that electric currents create magnetic fields. British scientist William Sturgeon invented the electromagnet in 1824. His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire (insulated wire didn't exist yet).The iron was varnished to insulate it from the windings.
