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.

Nov 15, 2016 The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 m, by using WHIMS2.

This is used to concentrate ferromagnetic particles such as iron of abrasion, magnetite and some pyrrhotites. The feed size is limited to 1 8 inch or even finer. Two well known usage are the concentration of magnetic taconite ores and the recovery of magnetite media in heavy media separation plants.
