Изобретение относитс к области разложени титановых концентратов серной кислотой в нронзводстве двуокиси титана.This invention relates to the field of the decomposition of titanium concentrates with sulfuric acid in the production of titanium dioxide.
Известен способ разложени титановых концентратов , заключающийс в обработке последних серной кислотой с перемешиванием воздухом, последующим подогревом реакционной массы, выщелачиванием плава и восстановлением трехвалентного железа.There is a known method of decomposition of titanium concentrates, which consists in treating the latter with sulfuric acid with air mixing, subsequent heating of the reaction mass, leaching of the melt and reduction of ferric iron.
Недостатками известного способа вл ютс низка степень извлечени двуокиси титана (до 92%) при разложении измененных ильменитовых концентратов, обусловленна образованием труднорастворимого соединени сернокислой соли титана и железа, а следовательно длительного процесса выщелачивани и невысока скорость фильтрации раствора на носледующих стади х передела.The disadvantages of this method are the low degree of extraction of titanium dioxide (up to 92%) during decomposition of modified ilmenite concentrates, due to the formation of a hardly soluble compound of titanium and iron sulfate salts, and consequently a long leaching process and a low filtration rate of the solution at the next stages of redistribution.
Предлагаемый способ отличаетс от известного тем, что восстановитель ввод т в реакционную массу непосредственно иеред ее подогревом . Это обеспечивает повышение степени извлечени двуокиси титана при разложении измененных ильменитовых концентратов до 95-96%.The proposed method differs from the known one in that the reducing agent is introduced into the reaction mass directly and is heated. This provides an increase in the degree of extraction of titanium dioxide during the decomposition of modified ilmenite concentrates to 95-96%.
Пример 1. В качестве исходного сырь берут ильменитовый концентрат следующего состава (в%): FeO 13,5; TiOa 59,6; FeaOg 21,4. В него ввод т 85%-ную серную кислоту в весовом соотношении 1:2 при перемешиваНИИ воздухом. К полученной смеси доба-вл ют восстановитель - металлическое железо и процесс дальнейшего разложени концентрата ведут по известному методу путем нагревани наром до температуры и выдерживани реакционной смеси при этой температуре. Извлечение двуокиси титаиа 95,7%.Example 1. As a source of raw materials take ilmenite concentrate of the following composition (in%): FeO 13,5; TiOa 59.6; FeaOg 21.4. 85% sulfuric acid is introduced into it in a 1: 2 weight ratio with mixing with air. The resulting mixture is added to a reducing agent, metallic iron, and the process of further decomposing the concentrate is carried out according to a known method by heating the nar to temperature and keeping the reaction mixture at this temperature. Extraction of titanium dioxide 95.7%.
П р и м ер 2. В качестве исходного сырь берут ил1зменитовый концентрат следующего состава (в %); ТЮа 63,0; РеО 1,0; РеаОз 23,0. В него ввод т 92%-ную серную кислоту в весовом отношении 1:2 при перемешивании воздухом . К полученной смеси добавл ют металлическое железо и ведут процесс по указанному методу при температуре 185°С.PRI m eper 2. As an initial raw material, take an il1-replaceable concentrate of the following composition (in%); TU 63.0; PeO 1.0; ReaOz 23.0. 92% sulfuric acid is introduced into it in a weight ratio of 1: 2 with air stirring. Metallic iron is added to the mixture and the process is carried out according to the indicated method at a temperature of 185 ° C.
Извлечение двуокиси титана 95,3%.Extraction of titanium dioxide 95.3%.
