Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
Dec 06, 2016 Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.
Different magnetic separators have different working principles, but most of them have the same feature of using magnetic force to attract magnetic substances to the surface of the device, and then transport these substances out of the magnetic area through belts or rollers/ drums to complete the separation. There are exceptions, for example, the eddy current magnetic separator uses the ...
Vertical ring and pulsating high gradient magnetic separator (VPHGMS) is designed Magnetic Jigging Principles, where the pulsation mechanisms assist in improving separation efficiency of magnetic minerals from non-magntics.
