| Abstract | The Ayatskoye deposit ore microstructure has been studied following magnetic-roasting processing. Reducing roasting of gravity-magnetic concentrate, produced from the Ayatskoye deposit ores, with subsequent magnetic separation, has been implemented. A thermodynamic analysis of possible processes in FeO → Fe2O3, Fe2O3 → Fe3O4 system with reducing roasting has been carried out. The run-of-mine ore and pyrite cinders Mossbauer analysis data, following gravity-magnetic concentrate roasting in presence of liquid hydrocarbons, are presented. A possibility of the Ayatskoye deposit brown iron ores dressing by means of magnetic-roasting processing method with preliminary treatment by liquid hydrocarbons in order to produce competitive concentrate has been determined. |
