  • Ore Beneficiation - an overview | ScienceDirect

    Due to the depleting reserves of DSO ores and increasing development of low-grade hematite and magnetite deposits, the need for iron ore beneficiation is increasing. Even the DSO ores are requiring a higher level of processing as the depth of existing mines is increasing (below water table) where ores are wet and more sticky, which creates challenges for conventional crushing and screening.

  • Beneficiation of Iron Ores – IspatGuru

    The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. 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

  • Understanding Iron Ores and Mining of Iron Ore

    High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace). Low grade iron ores containing lower iron content need beneficiation activities other than crushing, screening and washing for increasing their iron content. To be competitive, iron ore mining need to be done on a very large scale. There are two
