| titleOfInvention | Method of processing of titanium-silicon containing concentrates |
| abstract | FIELD: metallurgy of rare metals; methods of processing of titanium-silicon containing concentrates. n SUBSTANCE: the invention is pertaining to the field of metallurgy of rare metals, in particular, to the methods of processing of quartz- leucoxene concentrates of Yaregsky deposit containing high concentrations of the secondary rutile-quartz aggregate and may be used for production of artificial rutile - the raw for production of titanium by a chloric method and pigmental titanium dioxide. The method of the processing provides that the initial flotation quartz- leucoxene concentrate of 0.1 mm coarseness is treated with ammonium fluoride at its injection in a mass ratio to the concentrate of(0.6-1.25 : 1), and at the temperature of 195-205°C. Titanium and silicon compounds separation at the thermal treatment of the produced product is conducted at the temperature of 295-305°C with sublimation of ammonium silicofluoride and production in the bottom of the artificial rutile containing 90-95 % of titanium dioxide. Sublimates of ammonium silicofluoride are treated with handle an ammonia water gained at fluorination of the source concentrate with production of sediment of a silicon dioxide and the solution of ammonium fluoride after separation of silicon dioxide sediment is evaporated with production of ammonium fluoride, which is fed back for fluorination of a new batch of the initial concentrate. The technical result of the method is simplification of the process, reduction of power inputs and reduction of consumption of fluorine-containing reactant. n EFFECT: the invention ensures simplification of the process, reduction of power inputs and reduction of consumption of fluorine-containing reactant. n 2 ex |
