Изобретение относитс к способам очистки водных растворов от мышь ка и может быть использовано в технологии получени чистых соединений вольфрама.The invention relates to methods for purifying aqueous solutions from arsenic and can be used in the technology for producing pure tungsten compounds.
Известен способ очистки кислых водных растворов от мышь ка, включающий их обработку хлорным железом, нейтрализацию раствора до рН 8-9 и отделение мышь ксодержащего осадка от раствора. Однако с помош;ью известного способа невозможно очиш;ать от мышь ка вольфрамсодержаш,ие содовые растворы.A known method of purification of acidic aqueous solutions from the mouse, including their treatment with ferric chloride, neutralization of the solution to pH 8–9 and separation of the mouse to the containing precipitate from the solution. However, with the aid of a known method, it is impossible to clear the mouse of tungsten-containing, soda solutions.
По предлагаемому способу довод т содержание щелочи в вольфрамсодержащих содовых растворах до 7-12 г/л, после чего ввод т 2-4-кратное количество хлорного железа, счита на содержание мышь ка. Это обеспечивает возможность очистки от мышь ка вольфрамсодержащих содовых растворов.According to the proposed method, the alkali content in tungsten-containing soda fluids is adjusted to 7-12 g / l, after which 2-4 times the amount of ferric chloride is used, based on the content of the mouse. This makes it possible to clear tungsten-containing soda solutions from the mouse.
Пример. В пульпу, полученную от содового выщелачивани шламов, содержащих 34,2% WOa, 12,6% ЗпОг, 2% РегОз, 3,7% As,Example. In the pulp obtained from soda leaching of sludges containing 34.2% of WOa, 12.6% of ZnOg, 2% of RegO3, 3.7% of As,

ввод т дополнительное количество соды до содержани 7 г/л. При этом концентраци мышь ка в растворе 0,2 г/л. К раствору приливают 50 мл раствора, содержащего 80 г/л хлорного железа. Пульпу отфильтровывают и после промывки кека получают раствор вольфрамата натри (47,5 г/л WOa) с содержанием мышь ка менее 0,01 г/л.An additional amount of soda is added to a content of 7 g / l. At the same time, the concentration of the mouse in the solution is 0.2 g / l. 50 ml of a solution containing 80 g / l of ferric chloride is added to the solution. The pulp is filtered off and after washing the cake, a solution of sodium tungstate (47.5 g / l WOa) is obtained with a mouse content of less than 0.01 g / l.
