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.
