Claims (3)

1. Способ получения глинозема песчаного типа при переработке низкокачественного глиноземсодержащего сырья способом спекания, включающий последовательное применение карбонизации и декомпозиции на стадии выделения гидроксида алюминия из алюминатного раствора в присутствии затравочной гидроокиси, отличающийся тем, что, с целью улучшения гранулометрического состава гидроксида алюминия, на стадии карбонизации вводят затравочную гидроокись с содержанием класса -45 мкм 80-100%.1. The method of producing sand-type alumina in the processing of low-quality alumina-containing raw materials by sintering, including the sequential use of carbonization and decomposition at the stage of separation of aluminum hydroxide from aluminate solution in the presence of seed hydroxide, characterized in that, in order to improve the particle size distribution of aluminum hydroxide, at the stage of carbonization a seed hydroxide is introduced with a grade of -45 μm of 80-100%. 2. Способ по п.1, отличающийся тем, что, с целью получения глинозема песчаного типа с содержанием классов 45-125 мкм не менее 75%, затравочное отношение на стадии карбонизации поддерживают в пределах 0,02-0,25 ед.2. The method according to claim 1, characterized in that, in order to obtain sand alumina with a grade of 45-125 μm of at least 75%, the seed ratio at the carbonization stage is maintained within 0.02-0.25 units. 3. Способ по п.1, отличающийся тем, что, с целью повышения агломерации мелких частиц затравки, при карбонизации используют добавку модификатора роста кристаллов.3. The method according to claim 1, characterized in that, in order to increase the agglomeration of small seeds of the seed, during carbonization, an addition of a crystal growth modifier is used.
