## CHAPTER-8 BENEFICIATION OF IRON ORES

2012-8-16 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 strengths of 10 to 20 kilogauss. These separators are used to treat weakly magnetic minerals, such as hematite.

2018-10-4 Magnetic separators are integral part of the low grade iron ore beneficiation systems. Roasting of low grade iron ores to increase their magnetization (i.e. hematite to magnetite conversion) extends the applicability of conventional magnetic separators. Magnetic separators are also used in certain iron recycling applications.

2016-12-4 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 resources, as well as disposal systems and some- times complicated water reclamation systems.
