· The present work provides information on the iron ores that form part of the mineral mix which, once granulated, is loaded onto the sinter strand where it is partially melted at a temperature of between 1250-1350 °C and undergoes a series of reactions that give rise to the formation of sinter. 15 PDF

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.
