2 Weak, medium, strong magnetic separator. According to the magnetic field strength, magnetic separator is divided into three types: weak magnetic separator (low intensity magnetic separator), medium magnetic separator and strong magnetic separator (high intensity magnetic separator). The weak magnetic separator is from …
The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence considered as waste. Mineralogical investigation indicates the presence of chromite and quartz as major minerals with minor fuchsite and …
2.1.4 Screen Magnetic Separator. Screen magnetic separator presents another magnetic technique for the cleaning of strongly magnetic minerals such as magnetite, based on the principle of magnetic agglomeration (Li, 2005 ).

In 2020 A. K. Das et al. also investigated the beneficiation behavior of low grade chromite ore for ferrochrome production by using wet shaking table and wet highintensity magnetic separator (WHIMS).
A magnetic separator is generally classified as low intensity if its maximum field intensity is less than about 2000 gauss (H= 1.6 x 105 A/m, B=0.20 T). 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
The latter property is exploited in the beneficiation of magnetite ores using low-intensity magnetic separation.
