MINERALS AND PROCESSING FEATURES OF ILMENITE-LEUCOXENE ORES OF PIZHEMSKOE DEPOSIT, MIDDLE TIMAN A. V. Ponaryadov Institute of Geology Komi SC UB RAS, SyktyvkarProspects of development of the mining industry in the Komi Republic are associated with the largest deposits of titanium -Yaregskoe and Pizhemskoe. New data on the mineralogical and technological properties of titanium ores will allow accelerating the development of these deposits and proposing effective technologies of titanium ore processing and enhancing the list of commodity products. The set of mineralogical and analytical methods was used (optical and electron microscopy, X-ray and X-ray fluorescence analysis). Ilmenite-leucoxene ores of Pizhemskoe deposit are of complicated character, different metals (isomorphic impurity, autonomous mineral phases) are present along with main ore components. The morphometric characteristics of grains of ilmenite-leucoxene ore point to the need to use combined methods of enrichment and utilization.Keywords: Pizhemskoe deposit, ilmenite-leucoxene ore, morphometric characteristics, technological properties.

In this paper new crystalline materials were developed with pronounced electromagnetic properties, derived from titanium minerals, on the base of Academician N. P. Yushkin concept about mineralogical geomaterial science. Titanium minerals (rutile, anatase, ilmenite and others) are carriers of useful components (elements) and unique structures (nanotubes, nanocomposites and others). Titanium minerals were modified by hydrothermal method. The doping of TiO 2 with silver was realized by solgel methods. The modified nanotubes of titanium dioxide by nitrogen and acid treatment were realized to study the influence of parameters (temperature, time of hydrothermal alkaline treatment, acid influence at washing, etc.) over nanomaterials properties. The characterization of minerals and synthesis products was realized by scanning electron microscope (SEM), TEM, SEAD, EDAX, X-ray fluorescence method, atomic force microscope (AFM), etc. We revealed the nature of the phases and the degree of crystallinity of TiO 2-Ag nanocomposites with controlled particle sizes and electronic characteristics. Nanotubes made of TiO 2 are an alternative material for waveguides with high data flow rates, compared to the materials used in fiber technology.

A high cost of TiO 2 nanoparticles and their demand in industry determine the timeliness of the hydrothermal method of synthesis of titanium dioxide nanotubes from the low-cost natural mineral raw materials. The starting material (non-magnetic fraction of gravity concentrate of titanium ore of Pizhemskoe deposit) and synthesized samples were characterized by scanning electron microscopy, X-ray diffraction and X-ray fluorescence methods.
