Аннотация: The research results of the process of lisakovsky gravitational magnetic concentrate (LGMC) solid-phase metallization using the highly reactive solid carbon reducing agent «direksil» are given in the article. There were set rational parameters of solid-phase reduction process of LGMC in the mine furnace providing the extent of its metallization of 20.4–88.6 %. It was determined the temperature range of solid-phase direct reduction of iron of 1150–1200 ºC providing the maximum rate and extent of iron oxides metallization, at the same time passing over emergence of the liquid phase — fusion. Use of «direksil» as a reducing agent allows raising metallization extent of LGMC in more than 3 times in comparison with furnace coke. In the article there are given diffraction patterns (X-ray patterns) of the metallized samples of LGMC characterizing phase structure and crystal structure of the obtained restoration products depending on the type of reducing agent. The physical condition of the metallization products obtained in the mode of solid-phase restoration allows using all known methods of separation of the metallized concentrate from the dead rock. The most preferable option of such separation includes methods of magnetic separation in view of contrast formed after the system metallization. Separation of magnetic and non-magnetic products after metallization is an obligatory element of the technological scheme of LGMC metallization since the total content of iron in initial concentrate does not exceed 49 %. At that depending on metallization extent the magnetic fraction can be used as a furnace charge component when smelting the conversion iron in the blast furnace (metallization extent is less than 40 %) or steelmaking in the electric furnace (metallization extent is more than 80 %).
