Magnetic Separation

This method is used in those cases where either ore or the impurities are of magnetic in nature. In this method, the powdered impure ore in the form of thin layer is allowed to fall on a rubber belt which moves horizontally over two rollers, one of which has electromagnetic attached it. As the ore particles roll over the belt, the magnetic component in the ore gets attracted towards the magnet. It gets collected in a heap while the non – magnetic component forms a separate heap.

Chromite Fe(CrO2)2 an ore of chromium is magnetic in nature and contains non – magnetic impurities casseterite (SnO2) is non – magnetic in nature while the impurities of iron and chromium are magnetic in nature. These can be separated by magnetic separation.


  1. Hi very good post, Got relevent information about Magnetic Separators. Thanks for the posting.

  2. Finally found another article about magnetic separation! Thank you for posting this. Doing a bunch of research for my company to try and figure out what types of Magnetic Separators I should buy. This will help me in my search! Thanks
