Iron Ore Sinter an overview ScienceDirect Topics
E. Donskoi, J.R. Manuel, in Iron Ore, 2015 4.2.2 Sinter. Low-temperature (< 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.
