Description

Хлорные методы переработки материалов, содерн аш,их молибден и вольфрам, вызывают все возрастающий интерес со стороны промышленности .Chlorine methods of processing materials, soder ash, their molybdenum and tungsten, are of increasing interest from industry.

Хлориды и оксихлориды молибдена и вольфрама при температуре хлорировани  обладают высокой упругостью своих паров и легко отдел ютс  от основной массы примесей.Chlorides and oxychlorides of molybdenum and tungsten at a chlorination temperature have a high elasticity of their vapors and are easily separated from the bulk of impurities.

Известны способы хлорировани  молибдената газообразным хлором , смесью хлора и кислорода, смесью хлористого водорода и воздуха и другие. Описаны также способы хлорировани  вольфраматов кальци  и железа взаимодействием с хлоридами серы или с хлором, насыш,енными парами хлористой серы и другими.Methods are known for the chlorination of molybdenum with gaseous chlorine, a mixture of chlorine and oxygen, a mixture of hydrogen chloride and air, and others. Methods are also described for the chlorination of calcium and iron tungstates by the interaction with sulfur chlorides or with chlorine, saturated sulfur chloride pairs, and others.

По указанным способам хлорирование молибдено- и вольфрамосодержащих материалов производитс  в интервале температур от 300 до 900°. При этом больша  часть сопутствуюш,их элементов также переводитс  в соответствующие хлориды.According to these methods, the chlorination of molybdenum and tungsten-containing materials is carried out in the temperature range from 300 to 900 °. Moreover, most of them are concomitant, their elements are also converted to the corresponding chlorides.

Различие в физико-химических свойствах хлоридов р да элементов позвол ет, как правило, использовать их дл  частичного разделени  фракциоиированной конденсациейОднако из-за малого различи  в упругост х паров, указанный метод не может быть использован дл  отделени  хлоридов или оксихлоридов молибдена и вольфрама от хлоридов алюмини  и железа, которые обычно  вл ютс  основными сопутствующими элементами.The difference in the physicochemical properties of the chlorides of a number of elements allows them, as a rule, to be used for partial separation by fractionated condensation. and iron, which are usually the main concomitant elements.

Этот метод требует дорогих и громоздких, гидрометаллургических устройств и очистки от алюмини  и железа растворов, содержащих молибаен или вольфрам.This method requires expensive and bulky, hydrometallurgical devices and cleaning of aluminum and iron solutions containing molybenum or tungsten.

Предложен новый способ очистки хлорнроизводных (хлоридов иль оксихлоридов) молибдена или вольфрама от примесей алюмини  и железа , не требующий последующей гидрометаллургической обработки, заключающийс  в том, что, с целью повышени  качества, степени очиA new method for purifying chlorine derivatives (chlorides or oxychlorides) of molybdenum or tungsten from aluminum and iron impurities, which does not require subsequent hydrometallurgical processing, is proposed, in order to improve the quality of
