Most of the iron minerals in a single magnetite ore are because of its simple composition, strong magnetism, easy grinding and easy separation, the weak magnetic separation method is often used. When the grinding particle size is greater than 0.2mm, most iron ore magnetic separation plants usually use one stage grinding-magnetic separation;

Magnetic Separation and Iron Ore Beneficiation –

Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.

CHAPTER-8 BENEFICIATION OF IRON ORES

Low intensity magnetic separators (LIMS) are used to treat ferromagnetic and highly paramagnetic minerals such as iron and magnetite. High intensity magnetic separators (HIMS) generally have field strengths of 10 to 20 kilogauss. These separators are used to treat weakly magnetic minerals, such as hematite.
