The possibility of efficient ilmenite decomposition by microwave treatment is shown. Temperature-time processing regimes have been determined, which provide complete decomposition of ore material and extraction of titanium dioxide evenly throughout the depth of ilmenite particles. It is established that the main parameter in microwave treatment, which leads to the disintegration of ilmenite into pseudobrookite and rutile is the applied energy. In the case of using low-power microwave ovens complete decomposition of ilmenite can be achieved by increasing the processing time. The process of obtaining pseudobrookite and rutile phases from ilmenite can occur at heating temperatures less than 900 ° C. The influence of raw materials powder dispersion on heating and intensity of phase transformations in material is studied. The use of submicron-sized ilmenite ore powder increases the maximum processing temperature by 70 degrees and allows to extract 12% more titanium oxide compared to the ilmenite powder with an average size of 5 μm. The advantage of the microwave method in comparison with heating in conventional furnace is shown. Product Description popup.authors Derevyanko Oleksandr V. Lytvyn Roman V.
