COMPARISON OF IRON ORE SINTER MINERALOGY QUANTIFICATION

Abstract

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.
