Щукина Е. С. и др. Получение титаносиликатных композиций… 218 E. S. Shchukina, Yu. G. Kiselev, L. G. Gerasimova Production of titanium silicate compositions from technogenic titanium containing waste of Khibiny ores' enrichment The low level of complexity in the processing of raw materials at mining and processing enterprises adversely affect the environment causing considerable damage to it. Meanwhile technological waste is a cheap source of raw materials for liquid products of functional purpose, particularly inorganic filler which are widely used in the manufacture of paints and building materials, paper, plastics, insulating and protective materials. Improved performance and physical and chemical properties of materials are achieved by optimizing the composition and dispersion of the particles. By the example of the research subjects received from the flotation waste nepheline ore-dressing, it has been shown that a high degree of homogenization to obtain fine mixtures (75 % of 3–4 micron fraction) composite filler powders the ultrafine grinding method achieved by using a planetary ball mill for a short period of time (at least 1 hours). The use of other grinding methods, for example by means of ball mill or a vibration such effect is not obtained. At the conditions of ultrafine grinding the ionization and amorphization of the surface layer of powder material particles (mechanical activated processing) are occurred. This increases its activity by reacting with organic and inorganic binding, and provides high performance. The obtained filler has been tested in the composition of temperature-controlled sealants and glues used in the aerospace industry, shipbuilding and electronics. To obtain such materials sphene and nepheline received from industrial tailings of Khibiny apatite-nepheline ore deposits are used. Key words: mineral concentrates, technological waste, titanium dioxide, anatase, mechanical-activated processing, sealant, glue, surface area, oil number.
