Изобретение относитс к способам очистки титансодержащих концентратов от сопровождающих примесей по методу селективного хлорировани и может быть использовано, например, в металлургии титана.The invention relates to methods for purifying titanium-containing concentrates from accompanying impurities by the method of selective chlorination and can be used, for example, in titanium metallurgy.
Известен способ очистки титансодержащих концентратов от сопровождающих примесей по методу селективного хлорировани , заключающийс в том, что исходный продукт хлорируют (хлором) при нагревании ( 350°С) в присутствии твердого углеродсодержащего восстановител .A known method of purification of titanium-containing concentrates from accompanying impurities by the method of selective chlorination, which means that the starting product is chlorinated (with chlorine) by heating (350 ° C) in the presence of a solid carbon-containing reductant.
Способ характеризуетс сложностью процесса (что обусловлено необходимостью предварительного окислительного обжига исходного продукта), а также невысокой степенью очистки исходного продукта (удал ютс в основном примеси железа, в то врем как другие примеси, включа ванадий, остаютс в конечном продукте).The method is characterized by the complexity of the process (due to the need for pre-oxidative roasting of the starting product), as well as a low degree of purification of the starting product (mainly iron impurities are removed, while other impurities, including vanadium, remain in the final product).
Е предлагаемом способе в отличие от известного хлорирование осуществл ют в расплаве хлоридов щелочных и щелочноземельных металлов при 500-600° С с использованием в качестве углеродсодержащего восстановител газообразных углеводородов, например , метана.In contrast to the known chlorination, the proposed method is carried out in a melt of alkali and alkaline earth metal chlorides at 500-600 ° C using gaseous hydrocarbons, such as methane, as the carbon-containing reducing agent.
При осуществлении способа в одну стадию достигаетс довольно высока очистка исходного продукта от всех (кроме окислов кремни и алюмини ) примесей. При этом железоIn the implementation of the method in one stage, a rather high purification of the starting product from all (except silicon oxides and aluminum) impurities is achieved. With this iron
и ванадий мог)т быть извлечены из расплава, например, электролизом в виде самосто тельного продукта. Пример. 100 г ильменитового концентрата смещивают с 500 г обезвоженного карналлита и загружают на зеркало расплава с 500-600° С, В реакционную зону противотоком подают смесь хлора, воздуха и метана в соотношении 3,1 : 1 : 1,6 соответственно. Процесс хлорировани ведут в течение 4 час. При этом примеси Mg, Мп, Са, Fe и V переход т в расплав, фосфор и сера переход т в газовую фазу, а в твердом остатке остаетс двуокись титана с окислами кремни и алюмини . Остаток отдел ют от расплава, получа концентрат двзокиси титана с содержанием 88,29% TiO и 2,32% FeO (в виде хлорида).and vanadium could be extracted from the melt, for example, by electrolysis as an independent product. Example. 100 g of ilmenite concentrate is displaced from 500 g of dehydrated carnallite and loaded onto the melt mirror at 500-600 ° C. A mixture of chlorine, air and methane in a ratio of 3.1: 1: 1.6, respectively, is fed in a countercurrent reaction zone. The chlorination process is carried out for 4 hours. In this case, the impurities Mg, Mn, Ca, Fe, and V are transferred to the melt, phosphorus, and sulfur are transferred to the gas phase, and in the solid residue remains titanium dioxide with oxides of silicon and aluminum. The residue is separated from the melt to obtain a titanium dioxide concentrate with a content of 88.29% TiO and 2.32% FeO (in the form of chloride).
Предмет изобретени Subject invention
Способ очистки титансодержащих концентратов от сопровождающих примесей путем хлорировани исходного .продукта в присутствии углеродсодержащего восстановител при нагревании, отличающийс тем, что, с целью упрощени процесса и повышени степени очистки, хлорирование осуществл ют в расплаве хлоридов щелочных и щелочноземельных металлов при 500-600° С с использованием в качестве углеродсодержащего восстановител газообразных углеводородов, например , метана.The method of purification of titanium-containing concentrates from accompanying impurities by chlorination of the original product in the presence of a carbon-containing reductant with heating, characterized in that, in order to simplify the process and increase the degree of purification, chlorination is carried out in the molten alkali and alkaline earth metal chlorides at 500-600 ° C using gaseous hydrocarbons, for example, methane, as a carbon-containing reductant.
