1. Introduction. Magnetic separation is a method to recover magnetic materials by magnetism difference between particles, which is mostly applied in the field of mineral processing and is cleaner and cheaper than other methods such as flotation [[1], [2]].According to the media (water or air), magnetic separation can be divided into wet …

stationary magnet array. The Low intensity magnetic separators are available in several types for vast number of duties and could be seen as split into two categories, i.e. dry separation and wet separation. The dry models are intended predominantly for material 2 to 200 mm in dry or nearly dry state like crushed iron ore.

A significant increase in the magnetic field gradient can be achieved by placing ferromagnetic bodies (such as balls, mesh or steel wool) into the magnetic field of a separator (Frantz, 1937).These bodies (usually called a matrix), generate, when magnetised, a high local field gradient of the magnitude as high as 5 × 10 4 T/m. This …

The magnetic separator is the main component of a magnetic system. A low-intensity magnetic separator usually uses a multi-magnet magnetic system. ... Weakly magnetic iron ores, such as hematite, need to be treated by a combined process of high-intensity magnetic separation and other separation methods. ... Magnetic …

From the published literature, it is found that wet high-intensity magnetic separators are widely accepted in the mineral industry (Pradip, 1994, Jena et al., 2015, Seifelnassr et al., 2013, Filippov et al., 2014), but the application of dry magnetic separation for hematite beneficiation is not adequately developed or reported.

Abstract. This chapter introduces the principle of how low-grade iron ores are upgraded to high-quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized …
