Изобретение относитс к области очистки щелоч ых вольфрамомолибденовых растворов от сонровождаюихих примесей и может быть использовано, нанри.мер, в гидрометаллургии вольфрама и молибдена.The invention relates to the field of cleaning alkaline tungsten-molybdenum solutions from the moon-bearing impurities and can be used, in nanometer, in the hydrometallurgy of tungsten and molybdenum.
Известен снособ очистки указанных растворов от сопровождающих примесей, например кремпи , иутем обработки исходного раствора раствором соли алюмини в соответствующей кислоте, например сол нокислым раствором хлорида алюмини нри обычной темнературе . Образующийс ири этом осадок, содержащий нримеси, отдел ют от раствора. Однако нри, осуществлении известного способа достигаетс достаточно глубока очистка исходного раствора от кремни , но не от фтора.A known method for cleaning these solutions from accompanying impurities, for example krempi, is known and the treatment of the initial solution with a solution of an aluminum salt in an appropriate acid, for example, with a hydrochloric acid solution of aluminum chloride at a usual temperature. The precipitate containing impurities that form is separated from the solution. However, by implementing a known method, a sufficiently deep purification of the initial solution from silicon, but not from fluorine, is achieved.
По предлагаемому способу процесс осажденй ведут нри 60-90°С. Это обеспечивает достаточно глубокое обесфторивание исходного раствора.According to the proposed method, the process of precipitation is conducted at 60-90 ° C. This provides sufficiently deep defluorization of the initial solution.
Пример. Раствор автоклавно-содового выщелачивани вольфрамомолпбдснового промПродукта , содержащий 3,о г/л фтора и 60 г/л соды, обрабатывают сол покислым раствором хлорида алюми)П1 с копцептрацисй алюмини 55 г/л нри . При этом получают раствор, содержащий 0.8 г/л фтора, и кек, содержащий лишь 12% трехокиси вольфрама. Из раствора может быть выделена вольфра шва кислота с содержапие.м 0,007% двуокиси крсмии .Example. A solution of autoclave-soda leaching of a tungsten-molar industrial product containing 3, about g / l of fluorine and 60 g / l of soda is treated with hydrochloric acid solution of aluminum) P1 with a 55 g / l aluminum concentration of aluminum. You get a solution containing 0.8 g / l of fluorine, and a cake containing only 12% tungsten trioxide. From the solution can be isolated tungsten acid acid with content of 0.007% of silicon dioxide.

Способ очпстки июлочпых вольфрамомолибденовых растворов от сопровождающих примесей путем их осаждени де ютвием раствора соли алюмини в соответствующей кислоте , иапример сол покпслого раствора хлорида алюмини , с последующим отделением образующегос осадка от раствора, отличающийс тем, что, с целью обеспечени глубокой очистки исходного раствора от фтора, процесс осаждени ведут при 60-90°С.The method of precipitating tungsten-molybdenum solutions from accompanying impurities by precipitating with deutvium a solution of an aluminum salt in the corresponding acid, and as an example, using a salt of an alternate solution of aluminum chloride, followed by separating the precipitate formed from the solution, characterized in that in order to ensure deep purification of the initial solution from fluorine, the deposition process is carried out at 60-90 ° C.
