why iron ore needs beneficiation

Nuberry: Iron Ore

- High iron (Fe) content of all products. - Low undersize of lump ore. - Breaks down less during handling and transportation, so customers receive a larger fraction of valuable lump ore. - Creates less dust during handling and transportation so there is less ore loss and less impact on the environment. - Has an excellent thermal shock resistance.

Microbially induced iron ore formation has been confirmed at Gunma iron ore mine, Japan [21]. Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy source), iron oxide particles having higher phosphorous contents were seen to be colonized by different bacterial cells.
