A Novel Approach for Utilization of Ultra-Fines Iron Ore

Abstract. The utilization of 30% cured mini-pellets was accompanied by the constant highest temperature (≈1400 °C) in combustion zone. On the contrary, the sinter prepared using 30% uncured mini-pellets showed the highest temperature (≈1471 °C) at the beginning of sintering process followed by a gradual decreasing in the temperature.
