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.
