Реферат:	eng: In the article, a new approach for solution of the problem of the complex non-waste processing of the hydromica schist with producing of the expanded material and additional products (metal and sorbent) is presented. The basis for this solution is the deep reductive melting of the hydromica schist with separation of the melt saturated with reducing gases into the silicate part of the standardized chemical composition and metal. A choice of the reductive melting method is conditioned by possibility to stabilize the chemical composition by the additional charging of the melt in the course of melting. Under changes of the temperature-time modes of melting, the redistribution of the chemical elements in the silicate part contributes also to the melt composition standardization. The stages of the iron oxides reduction depending on the hydromica schist melting time are shown. A saturation of the melt with the reducing gases and formation of carbides in the melt are necessary conditions for the melt foaming, both in the course of melting and on its cooling into water under conditions of thermal shock. The foamed X-ray amorphous material (solid foam) produced in the course of such cooling has the bulk density of 65 kg/m3. The chemical composition of the metal obtained is close to that of ferrosilicium. After the hydrophobizing treatment, the above foamed material can be used as a sorbent for cleaning of water from organic substances including oil products. © National Society of Environmental Science and Engineering (SNSIM).
