Description
(54) СПОСОБ ЭКСТРАКЦИОННОГО РАЗДЕЛЕН1-1Я В . ЛЬФРАМА(54) METHOD OF EXTRACTION DIVIDED 1-1. LFRAMA
И МОЛИБДЕНАAnd molybdenum
Изобретение относитс к области гидрометаллургии вольфрама и молибдена.This invention relates to the field of hydrometallurgy of tungsten and molybdenum.
Известен способ экстракционного разделени вольфрама и молибдена, при когором молибден экстрагируют органическими эксг- рагентами, например ацетофеноном из сол нокислой пульпы вольфрамовой кислоты. Однако этот метод требует очень большого расхода сол ной кислоты (8т технической кислоты на 1 т концентрата).The method is known for the extraction separation of tungsten and molybdenum, in the case of which the molybdenum is extracted with organic extractants, for example acetophenone, from hydrochloric acid pulp of tungstic acid. However, this method requires a very large consumption of hydrochloric acid (8 tons of technical acid per 1 ton of concentrate).
По предлагаемому способу экстракционное разделение вольфрама и молибдена провод т в присутствии пррекиси водорода.According to the proposed method, the extraction separation of tungsten and molybdenum is carried out in the presence of hydrogen proroxide.
Это создает услови , обеспечивающие возможность полного разделени вольфрама и молибден а из кислых растворов в широком инвале кислотности и улучшает показатели процеThis creates conditions that allow the complete separation of tungsten and molybdenum from acidic solutions in a wide range of acidity and improves process performance.
Сущность предлагаемого способа заключаетс в следующем.The essence of the proposed method is as follows.
В раствор ввод т перекись водорода. В присутствии последней вольфрамова кислота не выпадает в осадок при любой кислотности . Кроме того, снижаетс степень полимеризации вольфрама и молибдена в растворе . Экстракционное разделение вольфрама Hydrogen peroxide is introduced into the solution. In the presence of the latter, tungstic acid does not precipitate at any acidity. In addition, the degree of polymerization of tungsten and molybdenum in solution decreases. Extraction separation of tungsten
молибдена, наход щихс в таких растворах , возможно пр: использовании органических экстрагентов различных классов.molybdenum contained in such solutions is possible: using organic extractants of various classes.
