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.

keywords Brown iron ores, extra-heavy oils, Moessbauer spectra, goethite-hydrogoethite concentrates, magnetizing roasting, magnetically-ordered phases.
