Magnetic Separation Method - Mineral Processing

Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as “Ferromagnetics”, those lesser (though noticeably) affected are known as ...

5.3 Magnetic Separation. Magnetic separations take advantage of the magnetic properties of minerals. All minerals will have one of three magnetic properties: ferromagnetic, paramagnetic, and diamagnetic. Ferromagnetic minerals (i.e., magnetite and pyrrhotite) are magnetic and are easily separated from other minerals, since they will be ...

Magnetic separation is to separate the magnetic impurity minerals and particles in the quartz sand. The quartz in the quartz sand is a diamagnetic substance, which cannot be magnetized in the magnetic field, and most of the impurities containing Fe and Ti are paramagnetic substances, which can be magnetized, so that the impurities containing Fe and Ti can be removed by magnetic separation
