The minerals and their composition of iron ore fluxed sinter are important factors on sinter qualities as the constituent of the matrix. The present work was carried out to predict the produced sinter mineral composition (hematite, magnetite, calcium ferrite and slag) prior to sintering with the use of material imformation. On the composition of sinter minerals, hematite and magnetite are determined with the iron oxide form and coke content in mix, and calcium ferrite and slag are influenced by SiO₂ and Al₂O₃ in mix. The model prediction was in relatively good agreement with the observed values by quantitative X-ray diffraction analysis.
