The manganese deposits of Bonai-Keonjhar belt in the Banded Iron Formation of Iron Ore Group occupy a significant position in mineral wealth of Orissa, Eastern India. The low to medium-grade manganese ores produced from this belt have low phosphorus content in contrast to the other two manganese deposits of Orissa.
