Description

Изобретение относитс  к производству глинозема, который  вл етс  источником получени  металлического алюмини .The invention relates to the production of alumina, which is a source for producing metallic aluminum.

Известен способ .разложени  алюминат ных растворов путем введени  в них активной затравки гидроокиси алюмини , полученной, например,, при самопроизволь ном разложении алюминатных растворов. Затравку готов т 8-1О суток. Степень разложени  апюминатных растворов составл ет 56,1%,The known method of decomposing aluminate solutions by introducing into them an active seed of aluminum hydroxide, obtained, for example, by spontaneous decomposition of aluminate solutions. The seed was prepared 8-1O days. The decomposition rate of apuminate solutions is 56.1%,

С цепью интенсификации процесса и повьгшени  степени разложени , предпагаатс  гидроокись алюмини  предваритепьно обрабатьгеать апюминатным раствором при постепенном снижении.температуры от 65 до .With a chain of process intensification and a higher degree of decomposition, it is assumed that aluminum hydroxide is pre-treated with an apyuminate solution with a gradual decrease in temperature from 65 to.

При этом возрастает скорость процесса в I, раза и степень разложени  на 5-8% (до 61,7%).At the same time, the speed of the process increases in I, times and the degree of decomposition by 5-8% (up to 61.7%).

Пример, Провод т сравнительную декомпозицию алюминатных растворов состава л. 132 г/л NcJ2O p128 г/пExample, Comparative decomposition of aluminate solutions of composition l is carried out. 132 g / l NcJ2O p128 g / p

том, полученным известным способом, и активной затравкой, полученной предпа гаемым способом.the volume obtained in a known manner and the active seed obtained by the proposed method.

Процесс разложени  провод т в течение 5О ч при равномерном снижении тем тературы с 65 до 43°С opt: затравочном отношении 1,0, и за 10, 22, 34 и 5О ч степень разложени  растворас активной затравкой соответственно составл ет 5О,7; 53,2| 55,9 и 61,7%,The decomposition process is carried out for 5 hours with a uniform decrease in the temperature from 65 to 43 ° C opt: a seed ratio of 1.0, and for 10, 22, 34 and 5 oh hours, the degree of decomposition of the solution with the active seed is respectively 5 O, 7; 53.2 | 55.9 and 61.7%,

При тех же услови х степень разложени  с известным затравочным, гидратом составл ет: 38,0( 12ч); 44,8(2Оч); 48,9(28 ч) и 56,1 (5О ч).Under the same conditions, the degree of decomposition with a known seed, hydrate is: 38.0 (12h); 44.8 (2Oh); 48.9 (28 h) and 56.1 (5O h).
