| Abstract | The results of the Lisakovskoye and Ayatskoye deposits' ores gravity-magnetic concentrates magnetizing roasting products' phase composition study by Moessbauer spectroscopy and thermomagnetic analysis methods over extra-heavy Kazakhstan oil are presented. It was ascertained, that pyrites cinders are magnetically-ordered phases, predominantly maghemite (γ-Fe2O3), of variable grade and order. |
