magnetic separation of material

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.

What Is Magnetic Separation? (with pictures)

Magnetic separation is an industrial process where ferromagnetic contaminants are recovered from materials on the production line. Manufacturers use this to extract useful metal, separate recycling, purify materials, and perform a wide variety of other tasks. Manufacturers of magnetic separation

What is magnetic separation? ChemistryRack

2021-8-3 The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.

Magnetic Separation of Gemstones

2009-6-25 Magnetic Separation of Gemstones Sylvia Gumpesberger Toronto, Canada INTRODUCTION Some gems are more magnetic than others, making magnetic separation of gem materials possible. Historically, this approach was hindered by the lack of strength of then available magnets, such as aluminum nickel cobalt (“Alnico”).

The disclosure describes apparatuses and methods of use thai may be used to remove material with magnetic properties from compositions, particularly pharmaceutical compositions. The apparatuses provide a conduit or column in which a magnetic field exists and through which a composition flows. Magnetic material in the composition is substantially reduced after flowing through the conduit or column.
