DEVELOPMENT OF OPTIMUM TECHNOLOGY REGIMES FOR PROCESSING TITANOMAGNETITE CONCENTRATES IN THE JEP UNIT

Abstract

For separation of titanium oxides into slag phase the electric arc furnaces are used in the existing technological schemes. A cheaper waste-free technology for processing titanium concentrate based on a continuous metallurgical jet-emulsion process (JEP) and unit was proposed. The following technological features of the new continuous metallurgical process JEP were considered: creation of a large reaction surface with subsequent organization of the forced movement of the formed gas suspension under pressure; implementation of the principle of gas-dynamic locking of the output channel in an oscillator reactor developed on the basis of this idea; creation of a non-equilibrium stationary oscillatory mode at a given pressure level; bottom supply of a two-phase working mixture prepared in an oscillator reactor to a vertical column reactor. The possibility of implementing a waste-free technology for processing titanomagnetite concentrates was substantiated, that simultaneously ensures the production of commercial titanium slag with smelting of the naturally alloyed metal. It was shown that the technology of almost complete separation of the iron-containing and titanium-containing components from titanium-magnetite concentrate is possible to implement in the JEP type unit in order to obtain the titanium slag with Ti2O5 content 46 % or more. The optimal consumption of materials was determined for complete reduction of iron and conversion of the titanium oxides into slag without formation of carbides.
