Magnetic Separation Method Mineral Processing amp; Metallurgy

Magnetic separation has two major applications in mineral processing plants The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.

Magnetic Mineral an overview ScienceDirect Topics

Magnetic mineral separation techniques are invariably selective, and not fully representative of the grain size and composition of magnetic minerals present in the sample; however, magnetic separation may be necessary for SEM/TEM, X ray, Mossbauer, or chemical analyses. The importance of fine SD grains as remanence carriers emphasizes the necessity of making the separation technique as sensitive as

Description Magnetite is a common mineral found at many localities in Wisconsin. Only localities that where the mineral is present in great abundance or as unusual material are listed here. Magnetite occurs as an accessory in most igneous, metamorphic and sedimentary rocks, where it is found as small equant, euhedral to rounded grains.
