Magnetic Separation and Iron Ore Beneficiation – IspatGuru

Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.CHAPTER-8 BENEFICIATION OF IRON ORESDer Waals, and capillary.

Magnetic Separator - an overview ScienceDirect Topics

The first step in any form of scrubbing unit is to break the lumpy materials and remove tramp elements by a magnetic separator. The product is then led into the scrubbing unit. The dry scrubbing principle is to agitate the sand grains in a stream of air so that the particles shot-blast each other.CHAPTER-8 BENEFICIATION OF IRON ORESDer Waals, and capillary.
