Description

Предлагаемое изобретение касаетс  способов получени  глинозема из кристаллического хлористого алюмини , представл ющего собою продукт растворени  глинозем содержащих материалов в сол ной кислоте.The present invention relates to methods for producing alumina from crystalline aluminum chloride, which is the product of dissolving alumina containing materials in hydrochloric acid.

В предлагаемом способе раствор хлористорого алюмини  подвергаетс  последующему выпариванию до насыщени  или превращени  в сиропообразную кристаллическую кашу, котора  затем, охлаждаетс , отдел етс  от маточного раствора отсасыванием и промываетс  20 /о-ной. сол ной кислотой, содержащей хлористый алюминий. Самый процесс осуществл етс  следующим образом.In the method according to the invention, the chlorine-aluminum solution is subjected to subsequent evaporation to saturation or conversion to a syrup-like crystalline porridge, which is then cooled, separated from the mother liquor by suction and washed 20 / o. hydrochloric acid containing aluminum chloride. The process itself is carried out as follows.

Прокаленную глину обрабатывают сол ной кислотой, большую часть отфильтровацной жидкости выпаривают до получени  кристаллической каши, содержащей, главным образом, кристаллический хлористый алюмин41Й, а хлористое железо в растворе. Эта кристаллическа  каша отсасываетс  и методически промываетс  растворами, получающимис  при обработке и обогащении остальной части вышеупом нутого отфильтрованного раствора вод ным паром, содержащим сол ную кислоту. Таким образом, получают изолированный, кристаллически чистый хлористый алюминий; хлористое железо при этом почти полностью удал етс  из кристаллической каши. В заключение кашу эту промывают свободной от железа сол ной кислотой, получаемой из другой порции газов-продуктов разложени  хлористого алюмини  путем сгущени  или промывки водой, или более слабой сол ной кислотой. Эта обогащенна  или насыщенна  хлористым алюминием кисдота может быть снова использована до тех пор, пока то допускает содержаThe calcined clay is treated with hydrochloric acid, most of the filter liquor is evaporated to obtain a crystalline porridge containing mainly crystalline aluminum chloride, and iron chloride in solution. This porridge is sucked off and methodologically washed with the solutions obtained by processing and enriching the rest of the above filtered solution with steam containing hydrochloric acid. In this way, isolated, crystalline aluminum chloride is obtained; the iron chloride is almost completely removed from the crystalline porridge. In conclusion, this porridge is washed free of hydrochloric acid from iron, obtained from another portion of the gas products of the decomposition of aluminum chloride by condensation or washing with water, or weaker hydrochloric acid. This acid-rich or aluminum chloride-rich acid can be reused as long as it allows
