Description

Примен ющиес  способы выделени  селена из камерного ила, как, например: окисление перманганатом , окисление бертолетовой сЪлью и цианистый метод обладают некоторыми недостатками. Первый способ не экономичен, вследствие высокой стоимости перманганат а и сравнительно низкого выхода селена-около 70%, второй и третий способы более экономичны, но требуют сложной аппаратуры и опасны, вследствие возможности взрывов при применении бертолетовой соли и отравлений при цианистом методе .The methods used for separating selenium from chamber sludge, such as, for example, oxidation with permanganate, oxidation with the bertoleta method, and the cyanide method, have several disadvantages. The first method is not economical, due to the high cost of permanganate a and a relatively low yield of selenium, about 70%, the second and third methods are more economical, but require complex equipment and dangerous, due to the possibility of explosions when using potassium chloride and poisoning with the cyanide method.

Предлагаемый способ выделени  селена из камерного ила, при помощи окислительного процесса с последующим восстановлением, имеет целью удещевить производство селена, применением дешевых окислителей - пиралюзита и серной кислоты.The proposed method for separating selenium from chamber sludge, by means of an oxidative process and subsequent recovery, is intended to make more expensive the production of selenium by using cheap oxidizing agents, piralusite and sulfuric acid.

Способ состоит в следующем:The method consists in the following:

250 т камерного ила загружаютс  в эмалированный котел с мещалкой и паровой рубащкой. При тщательном перемешивании к нему приливаетс  150 ш серной кислоты. Смесь нагреваетс  до 90 - 95° и к ней понемногу добавл етс  при непрерывном перемешивании порощок пиролюзита в количестве 35 z Полученна  таким образом селениста  кислота выщелачиваетс  водой и осаждаетс  бисульфитом натри . Выход-90%.250 tons of chamber sludge are loaded into an enamelled boiler with a broom and a steam jacket. With thorough mixing, 150 pounds of sulfuric acid are added to it. The mixture is heated to 90-95 ° C and a pyrolusite powder in the amount of 35 z is gradually added to it with continuous stirring. 35 z The selenide acid thus obtained is leached with water and precipitated with sodium bisulfite. Yield-90%.

, Предмет патента.The subject of the patent.

Способ выделени  селена из камерного ила при помощи окислительного процесса с последующим восстановлением, отличающийс  тем, что окисление ведут при помощи пиролюзита и серной кислоты при нагревании, после чего образующуюс  селеновую кислоту восстанавливают известным способом.A method for separating selenium from chamber sludge using an oxidative process followed by reduction, wherein oxidation is carried out with pyrolusite and sulfuric acid when heated, after which the selenium acid formed is reduced by a known method.
