Summary of Iron Ore Beneficiation Process and Technology

There are many mineral processing methods, and there are two commonly used methods (1). Roasting magnetic separation Roasting magnetic separation is one of the effective methods to separate fine to fine (< 0.02mm) weakly magnetic iron ore. When the minerals in ore are complex and it is difficult to get good indexes by other methods, magnetization roasting magnetic separation should be used.

Magnetic Separation and Iron Ore Beneficiation - IspatGuru

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.
