magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water
Magnetic elutriation improves the quality of low-grade domestic iron ore by using an alternating-current, pulsed-magnetic field to clean iron ore into a highly refined product. This innovative process differs from conventional drum type magnetic separation systems by using permanent magnets that cause magnetic entrapment.

R.J. Holmes, in Iron Ore, 2015. 9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15%

Der Waals, and capillary. 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
Jan 01, 2019 Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used,. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced

Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 µm down to –10 µm.

Aug 01, 2011 A laboratory experiment was carried out to extract iron from oolitic iron ore by a deep reduction and magnetic separation technique. The raw coal with fixed carbon of 66.54% was used as the reductant. The iron was successfully extracted from the oolitic iron ore which otherwise is nearly impossible to be separated due to its extremely fine-grain and mosaic nature.
