Understanding the high-grade iron ore market

2021-3-26  In the BF, iron ore is melted at a high temperature, along with fluxes, producing molten iron and a ‘slag’ that physically removes impurities such as silica and alumina. In the DR furnace, however, iron oxide is reduced in situ, with temperatures sucient to remove the oxygen but not high enough to fully melt the ore. No fluxes are introduced to remove impurities from the final direct-reduced iron (DRI) either. For this reason, silica and alumina ores
