    Iron Ore Sinter an overview ScienceDirect Topics

    Lowtemperature 1300 °C iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles 1 mm and a matrix bonding phase produced from the melting of fine ore − 1 mm and flux particles with the majority of melt formation occurring in the granule adhering fines layer The majority of nuclei are hematitic but they can also be any other unreacted particles such as flux or aluminosilicate
