CHAPTER-8 BENEFICIATION OF IRON ORES
BENEFICIATION OF IRON ORES A. Das and S. Roy INTRODUCTION Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite

Appropriate beneficiation process has to be advanced to reduce the waste generation in mines and for the sustainable growth of the iron ore industry some. Major reason for difficulty in beneficiation of BHJ is revealed from characterization studies which show the intergrowth of haematite and quartz. Presence of Kaolonite is proved with the aid of mineralogical studies. For the separation of

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2"). Pellets are screened to meet the size specification
Iron Ore Beneficiation Process
During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable
