Smirnova G. The applied mineralogy of sulfides of Inguletz deposit ferruginous strata (Krivoy Rog basin)".

3. The peculiarities of mineralogical zoning of ferrugiuons and shist horizons of Inguletz deposit saxagan suite and of sulphides (pyrite, pirrhotite) distribution in their sections are considered. The sedimentation, dynamothermal metamorphism, sodic metasomatosis and hypergenesis role distribution within deposit productive strata is shown. The peculiarities of pyrite and pirrhotite behaviour in process of poor magnenite ores (ferriferous guartzites) crushing and dressing are revealed with use of experimental mineralogy-technological data. The ores mineral varieties wich cause the increased sulphur content in magnenite concentrate of Inguletz mining- and processing integrated works are defined. The mineralogical recommendations to increasing the concentrate quality are worked up.
