Low grade Iron Ore Beneficiation and the Process of

Hence, the scenario is steadily shifting towards the use of low grade iron ores and slimes which are stock piled in the mine’s sites for years. These dumped slimes also, in fact, falls in the category of low grade iron ore. Also, some of the ores of iron have a complex mineralogical composition and do not respond to conventional beneficiation techniques.
