Description
Известно, что при спекании или силазленни корунда, боксита или других содеризщкх окись алюмини минералов с едкими или углекислыми щелочами, щелочными сол ми, а также с окислами и углекислыми соединени ми щелочноземельных металлов, образуютс соответственные алюминаты щелочных или щелочно-земельных металлоз.It is known that sintering or strength of corundum, bauxite, or other aluminum oxide minerals with caustic or carbonic alkalis, alkaline salts, as well as oxides and carbonic compounds of alkaline earth metals, forms alkaline or alkaline earth alkaline aluminates.
При дальнехщем выделении известными способами из полученных алюминатов окиси алюмини получение чистого продукта представл ет известные затруднени . При выщелачивании сплава в раствор переходит, кроме глинозема, также и значительное количество кремнезема, вследствие чего необходимы сложные методы очистки растворов дл получени чистой окиси алюмини .With further isolation by known methods from the obtained alumina alumina, obtaining a pure product presents known difficulties. When leaching an alloy, a significant amount of silica, besides alumina, also passes into the solution, as a result of which complex methods of solution cleaning are necessary to obtain pure alumina.
Указанные затруднени устран ютс , если употребл ющиес алюминий содержащие минералы подвергнуть предаарительной восстановительной плавке в электрической печи, причем кремнезем будет удален в форме ферросилици . Полученный при этом искусственный корукд с расплавленном виде переводитс в другую печь, где и производитс присадка необходимого количества щелочных или щелочно - земельных соединений. Поскольку реакци между расплавленным корундом и щелочами протекает весьмаThese difficulties are eliminated if the consumed aluminum-containing minerals are subjected to a preliminary reduction smelting in an electric furnace, and the silica will be removed in the form of ferrosilicon. The resulting molten artificial korukd is transferred to another furnace, where the necessary amount of alkaline or alkaline-earth compounds is made. Since the reaction between molten corundum and alkalis proceeds very
быстро, добазлениа последних может быть произведено в самый момент г;ь:пуска расплавленного корунда путем Едувани или вмещивани в него щег.очнс;х или щелочно-земельных соединений. Полученные таким способом алюминаты мо- гут быть подвергнуты в дальнейшем обычным известным методам переработки , например, выщелачквгн/.ю и карбонизации .quickly, the release of the latter can be done at the very moment r; ь: the start-up of molten corundum by Eduvani or by enclosing herbalbearing x or alkaline-earth compounds in it. The aluminates obtained in this way can be further subjected to the usual well-known processing methods, for example, leaching and carbonization.
