Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a lowgrade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron recovery of 90%.

Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. The process that is used for magnetic separation separates nonmagnetic substances from those which are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron, nickel, and cobaltcontaining minerals) and paramagnetic.
