Titanomagnetite and ilmenite ores are promising raw materials for the extraction of iron, titanium and vanadium. It is shown that the two-stage method of processing is the most effective in terms of extracting all valuable elements and does not contribute to the formation of man – made waste as with the hydrometallurgical method and the ‘Blast furnace – BOF’ scheme. At a temperature of 900, 1000 °C in the CO atmosphere, the kinetics of the reduction process is small and the metal phase is not fixed by X-ray phase analysis methods, but some grains have a metal phase. It is shown that the extraction of iron from the ilmenite crystal lattice is accompanied by the release of the TiO2 phase. At a low temperature of 900, 1000, 1100 °C, the dissolution kinetics of TiO2 is small. At a higher temperature of 1200, 1300 °C, the TiO2 phase is dissolved in the ilmenite phase, and the crystal lattice changes to form the FeTi2O5 phase.
