Magnetic Separation and Iron Ore Beneficiation

Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Iron ore beneficiation, flotation or magnetic

2011-10-27  Iron sand mining equipment is suitable for wet magnetic separation of materials such as magnetite, calcined ore, etc. and it can remove the iron in the coal, non-metal and construction industries. The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel.

BENEFICIATION OF BOREHOLE IRON ORE SAMPLES

Because of the fine dissemination of the iron minerals and the most abundant gangue mineral, the particles size of ore was set at 80% passing 150 meshes. Rougher tests of magnetic separation produced concentrates with iron content of about 58.2% Fe; the tailing of rougher stage was then scavenged using higher magnetic intensity.

A Beneficiation Study on a Low Grade Iron Ore by

In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity methods showed
