Nov 25 32 The process of sintering is a thermal operation involving melting and assimilation reactions The first stage of the sintering process is the formation of the melt which involves the reaction between fine iron ore particles and flux The initial melt is generated from adhering fines during heating via reaction between iron ore and fluxThe level of impurities and loss on ignition in iron ore has also been slowly increasing Finally the proportion of fine material in the available products has increased considerably for most iron ore fin This has been found to have significant impacts on sinter quality and sintering performance
