Concentrate Grade
In summary, magnetic separation should always be given priority when designing iron ore beneficiation flow sheets. For some oxidized iron ores, the selectivity of high-intensity and high-gradient magnetic separators may not be as good as other methods. Nevertheless, they can reject most of the gangue minerals if they are used at the roughing stage.

Iron ore beneficiation: an overview
However, due to the growing demand for iron ore, this is not sustainable; in India, the cut-off grade is now revised to 45% Fe by the Indian Bureau of Mines for hematitic and geothitic ores. Hence, the low-grade iron ore needs to be beneficiated to make the iron ore concentrate suitable for iron-making process.

Review of organic binders for iron ore concentrate agglomeration …
Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make …
