Description
Предлагаемый способ получени глинозема в отдельных част х аналогичен способу Калунит. Так же, как в последнем способе, выщелачивание руды производитс оборотным раствором серной кислоты и сульфата щелочного металла. Однако в способе Калунит разложение квасцов с образованием основных квасцов достигаетс обработкой раствора при температуре 200° С.The proposed method of producing alumina in parts is similar to the Kalunite method. As in the latter method, the leaching of the ore is carried out with a circulating solution of sulfuric acid and an alkali metal sulphate. However, in the Kalunit method, the decomposition of alum with the formation of basic alum is achieved by treating the solution at a temperature of 200 ° C.
По предлагаемому способу разложение квасцов достигаетс при длительном перемешивании раствора с затравкой при температуре пор дка 100° С.In the inventive method, the decomposition of alum is achieved with prolonged stirring of the solution with seed at a temperature of about 100 ° C.
Способ заключаетс в том, что глиноземсодержащую породу (глины, алуниты и т. п.)выщелачивают известными приемами оборотным раствором , содержащим серную кислоту и сульфат щелочного металла.The method consists in that the alumina-containing rock (clays, alunites, etc.) is leached by known techniques with a working solution containing sulfuric acid and alkali metal sulfate.
К полученному раствору квасцов добавл ют некоторое количество основной соли алюмини и щелочи (наприллер 450з ЭНаО) в качестве затравки и перемешивают при температуре пор дка 100° С или несколько выше при соответствующем давлении до тех пор, пока из раствора вследствие гидролиза не выпадет достаточное количество (например, 50%) глинозема в виде основной соли того же состава, что и затравка. Перед «выкручиванием ) раствор может быть несколько разбавлен, в конце «выкручивани тел1пература может быть несколько понижена.To the resulting solution of alum, add some amount of basic aluminum and alkali salt (napriller 450z ENAO) as a seed and stir at a temperature of about 100 ° C or slightly higher at an appropriate pressure until a sufficient amount ( for example, 50%) of alumina in the form of a basic salt of the same composition as the seed. Before "unscrewing" the solution may be somewhat diluted, at the end of "unscrewing the body," the temperature may be slightly reduced.
Выпавша основна соль отфильтровываетс и может быть переработана далее известными способами, например, термическим1 разложением (с получением алюлшнатов), разложением аммиаком (с получением глинозема и сульфата аммони ) и т. д.The basic salt that is precipitated is filtered out and can be further processed by known methods, for example, by thermal decomposition (to produce aluminates), by decomposition by ammonia (to produce alumina and ammonium sulfate), etc.
Маточный раствор от кислотного «выкручивани идет на выщелачивание новых порций породы, причем недостающа серна кислота пополн етс либо за счет термического разложени основной соли, либо вводом ее со стороны.The mother liquor from acidic spinning is used to leach new portions of the rock, and the missing sulfuric acid is replenished either by thermal decomposition of the basic salt or by introducing it from the side.
