Abstract As per national steel policy vision 2030 around 500 million tons of quality iron ore is required to produce 300 million tons of steel In this context the use of low grade banded iron ores Fe 3045 4050 silica is inevitable Reduction roasting followed by magnetic separation technique is employed to treat such ore In this work banded iron ore with 32 Fe is enriched to a grade iron ore to produce quality raw material would play a key role in future which is a fact acknowledged by the iron and steel industry 12 India is bestowed with rich iron ore reserves in the form of hematite and magnetite Most of the iron ore mines produce hematite ores and have washing plants to produce lumps as well as fines
