Study of the iron ores of the Ayat deposit of the oolite type

The paper presents the results of studies of the composition of the oolitic iron ore of the Ayat deposit. Experiments were carried out and the results of the study of the decomposition of brown ironstone in the oxidizing atmosphere are presented. Analysis of the chemical composition of the initial and burnt ore was carried out using an electron microscope (micro X-ray spectral analysis), and also by the chemical method. The study of the mineralogical composition of the initial and burnt ore was carried out on a diffractometer by X-ray diffraction analysis. The obtained data are necessary for the development of theoretical and technological bases of pyrometallurgical processing of oolitic iron ores with high phosphorus content.
