Magnetic Separation

This kind of magnetic separator has been widely used in the separation of hematite and other weakly magnetic iron ore. However, slightly coarse ore mechanical inclusion and magnetic field space blocking are found in the use of this type of machine, thus the production cannot run normally. ... Some nonmetallic ores, such as kaolin, cinnamon sand ...

Assessing the performance of a novel pneumatic magnetic separator for

Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low-grade 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%.
