Low grade Iron Ore Beneficiation and the Process of
Modern beneficiation processes allow for effective and low cost upgrading of lump, fines and ultra-fines of such ores. Since the iron ores consist of several compositions, mineralogies, shapes, and sizes, so there is no ‘one size fits all’ approach to the beneficiation of iron ore. Most of the ‘run-of-mine’ (ROM) iron ore contain a large percentage of other materials which need to be

Beneficiation of Iron Ores IspatGuru
Grade of iron ore is usually determined by the total Fe content in the ore. Run of mines ores after dry or wet sizing, if it contains normally greater than 62 % of Fe, are known as ‘natural ore’ or ‘direct shipping ore’ (DSO). These ores can be directly used in the production of iron and steel. All other ores need beneficiation and certain processing before they are used in the
