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 ...

It's popularized that dry permanent magnetic separator for coal separation in order to achieve desulphurization and dust reduction to ease enviromental pollution. However, due to weak magnetic coal minerals, conventional magnetic separator is far from for effective separation of fine coal. This paper proposes a new type of permanent magnetic separator with unique magnetic system structure ...

This paper describes the construction and performance of an alpha prototype MagMill TM processing bituminous coal at 90 kg/hr. The prototype consists of an air-swept hammermill, which has been modified for withdrawal of a continuous stream of hard material separated from its internal circulation. The mineral-rich stream is sent to an attached ParaMag TM magnetic separator for rejection of ...

In similarity to triboelectrostatic separation technology, dry magnetic separation technology also requires that the feed coal has high degree of dissociation in order to facilitate the separating process of coal and gangue depending on magnetic susceptibilities difference. Meanwhile, dry magnetic separation technology also has comparative small handing capacity.
