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.,

Magnetic separation is one of the methods that has been used for almost 200 years in the concentration of iron ores and is still used extensively even today. Most common used magnetic separation process is carried out on a drum separator [3]. Magnetite is

gangue minerals from iron ores. However, the ores having ferromagnetic nature are suitable for being processed using magnetic separation methods For example, magnetite [1]. (Fe 3O 4) is the most ferromagnetic of all the naturally occurring minerals on earth, and therefore -intensity magnetic low separators are widely used to upgrade magnetite ores.
