  • Effect of pyroxenite and olivine minerals as source of

    Pelletization of hematite ore requires high fineness and very high induration temperature (~1325 °C) owing to its poor diffusion bonding unlike magnetite ore. Further, high-alumina hematite pellets show very high reduction degradation index (RDI) during low temperature (500–650 °C) reduction due to their volume expansion and lattice distortion.
