“…Under a Teflon-lined autoclave, ilmenite will settle to form a precipitate due to its relatively high density of about 2400-2700 kg/m 3 [18] and only the upper part of the precipitate reacts to form hydrogen titanate as a result. Another phase that may appear is quartz, which has been previously reported by several researchers [19,20]. Figure 2 depicts an image of SEM testing on a precursor material in the form of an ilmenite mineral.…”

Titanate nanosheets are a type of 2-dimensional nanomaterial with vast applications in electronics, energy storage, and photocatalysis due to their superior properties, such as their large specific surface area and excellent electrical conductivity. Titanate nanosheets are expected to be the material precursor of TiO2 nanostructures with further treatment. The current research aims to synthesize titanate nanosheets using the natural mineral ilmenite from Indonesia through the hydrothermal method. X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunaeur-Emmett-Teller (BET) analysis were used to characterize the chemical composition, crystal structure, shape, size, and specific surface area of the prepared samples. The structure phase of the as-synthesized sample is known to be layered titanate. The as-synthesized nanosheet sample has a diameter ranging from 2.5 to 4 μm and BET surface areas of approximately 40 m2/g. This concise hydrothermal method could create 2-dimensional structured nanomaterials from Indonesian local minerals.

We present a comparative evaluation of efficiency of titanium dioxide polymorphs as an active photocatalyst (commercially available DegussaP25, anatase (Sigma Aldrich), natural leucoxene concentrate (Pizhemskoe deposit, Russia) and titanium dioxide nanotubes based on it). The materials obtained on the basis of relatively inexpensive and affordable ilmenite-leucoxene ore have the same efficiency as more expensive commercial products.

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.
