At present, the powder XRD is widely used analytical method for iron ore sinter mineralogy determination. In many types of research, diffraction data for SFCA and SFCA-I phases were not available, and diffraction data for other calcium ferrites were used instead. Therefore, the aim of this paper is to bring a comparison between the evaluation of diffractograms, when SFCA/SFCA-I, and, other calcium ferrites, respectively, are considered. As a result, the quantification of phases is quite comparable, when minerals are collected into groups, i.e. hematite, magnetite, calcium ferrites, silicates and non-assimilated non-ferrous phases. Only in the case of silicates, a comparison tends to be dissatisfactory.
