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.
