Mar 27, 2018 Low grade iron ores cannot be used as such for the production of iron and SST eel and need to be upgraded to reduce its gangue content and increase its Fee content. The process adopted to upgrade the Fee content of air n ore is known as iron ore benefaction 108.
removal of over-burden, drilling and blasting. Iron is then transported to beneficiation plants where it is crushed, washed and screened according to its grade 3. However, during these beneficiation processes, fines are inadvertently produced. These fines are separated from the lump ore through the use of screens, classifiers and cyclones 3.

Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.
