All lean magnetite ores need to remove gangue minerals such as quartz through weakly magnetic field magnetic separators to improve the iron grade of concentrate. Weakly magnetic iron ores, such as hematite, need to be treated by a combined process of high-intensity magnetic separation and other separation methods.
For processing of low-grade iron ores, ground to finer size necessitates the use of centrifugal force. This is because the settling rate of the particles in centrifugal force is 500–600 times more than that noticed for the nominal gravitational force. Multi-gravity separator (MGS) is the one such unit used for recovering hematitic fines… Expand

ica from weakly magnetic ores such as hematite are substantial [13, 15, 16]. The biggest problems facing conventional WHGMS/WHIMS separators are matrix dogging and the mechanical entrainment of non-magnetic particles when it is applied to treat metallic ores, including hematite ores [1, 20]. For hematite ores, the various Wet High-Intensity Mag-
