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.

Efficiency Evaluation for Titanium Dioxide-Based Advanced Materials in Water Treatment

“…There are weak reflexes of ilmenite and anatase. Leucoxen is a rutile microcrystalline matrix, saturated with the finest inclusions of quartz (Ponaryadov 2017). The synthesized sample (Fig.…”

Comparative study of stages of titanium minerals formation in nature and experiment for “smart” materials industry

“…The intrigue lies in comparing the algorithms of natural and technogenic phase transformations of titanium minerals on the way from rocks (raw materials) to "smart" materials: at what stage should humans take lessons from nature, at what stage does a human do better than nature and takes into account environmental and economic risks? Titanium minerals are often used as test objects to solve problems of their constitution and properties [10][11][12][13][14], etc. and concluded that the classification of mineral formation processes, both in nature (mineralogenesis) and in their transformations during technological processing (technogenesis), depends on the energy and the source of the substance, the nature of the environment where this process occurred, and types of chemical reactions.…”

“…Study of the processes and conditions in which natural titanium minerals are formed (mineralogical scenario) [14,[28][29][30], study of crystallography and crystal chemistry of natural titanium minerals help technologists (chemists) to synthesize titanium minerals. Synthetic analogs of natural oxide forms have fundamentally new structural features and industrial properties.…”

“…The authors proposed to carry on a comparative study the relationship between the stages of mineralogenesis processes and their transformations during the technogenesis of titanium ores in nature and experimentally. The Pizhemskoe deposit (Russia) has been sufficiently studied [14,29] and is ready to start as exploited to guarantee the authors' arguments the proper level of credibility. Despite the existing scientific work, there are no comparative studies of the stages of the processes of mineral formation of titanium ores in nature (mineralogenesis) with experiment (technogenesis) under hydrothermal conditions.…”

Genetic Problem of Quartz in Titanium Minerals in Paleoplacers of Middle Timan

“…Slates of the Precambrian folded basement of the Timan are the root source of titanium minerals. Titanium paleoplacers are formed due to the redeposition of the weathering crust on shale (Kochetkov 1967;Kalyuzhny 1972;Makhlaev 2006;Ponaryadov 2017).…”
