The Banded Iron Formation (BIF) is an important volcano-sedimentary rock formation of the Iron Ore Group (IOG) of Singhbhum and Orissa. The Precambrian IOG, ~3.1–3.3 Ga in age, contains metavolcanic and meta-sedimentary rocks, shales and tuffs that underlie or are interlayered with the BIF, which consists of the units of Banded …

The iron ore fines sample was collected from the spiral classifier overflow of a typical Iron ore beneficiation plant of Noamundi, India. The sample was dried, thoroughly mixed and analysis indicated that the dried sample contained 59.77% of total iron, 5.89% alumina and 4.71% silica with an LOI (Loss on Ignition) of 5.53%.
