Keywords: magnetic separator; permanent magnet; dry pre-sorting; iron ore; review 1. Introduction Dry magnetic separation is a technology that sorts magnetic minerals from gangue using air as the medium instead of water. When raw ore is fed to the magnetic separator, the magnetic particles are subjected to magnetic force due to the Dry medium-intensity magnetic separator (DMIMS) plays a vital role in enhancing the separation of low-grade raw magnetite ore. A good understanding of the dynamic separation process of DMIMS would further boost its economic competitiveness in minerals processing and engineering.

Dynamic behavior and separation prediction of magnetic ore bulks in dry
1. Introduction. The past decades have witnessed tremendous progress made in the magnetic separation technology that have significantly decreased the industrial grade of mined iron ore (Liu et al., 2020, Zeng et al., 2019).However, the extensive energy consumption and high capital costs required in utilization of low-grade iron ore still render Abstract: Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is further beneficiation is restricted to the procedure of dry magnetic separation.

Further, magnetic separation studies of low grade iron ore was carried out by using IRMS and found that a product of maximum of 51.2% Fe can be separated from the low grade ore assaying 35.9% Fe (Tripathy et al., 2014). Separation results are analyzed based on the Box-Behnken method and maximum responses (grade in terms of iron, The dry magnetic separation of original steel slag was performed with different slag sizes (<0.074, 0.074–0.109, 0.109–0.15, 0.15–0.38, and >0.38 mm) and different magnetic intensities (180, 250, 280, and 300 mT).

Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low-grade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron recovery of 90%.The utility of magnetic separation in iron ore beneficiation has been widely reported earlier (Pradip, 1994, Jena et al., 2015, Das et al., 1991, Li et al., 2010, Song et al., 2002, Raj et al., 2007, Seifelnassr et al., 2013, Tripathy et al., 2014).

Magnetic separation studies for a low grade siliceous iron ore sample
The investigations carried out on the low grade iron ore sample reveal the following conclusions. (1) The sample on average contains 43.8% Fe, 16.8% SiO 2 and 5.61% Al 2 O 3. (2) The mineralogical studies indicate that the major iron minerals are magnetite, hematite and goethite. And the gangue minerals are silicates and calcites.
