Изобретение касаетс переработки каолина сернокислотным способом с получением глинозема и других продуктов.The invention relates to the processing of kaolin by the sulfuric acid method to produce alumina and other products.
Известный способ переработки каолина на глинозем состоит в том, что .каолин обжигают при 560-580°С, обрабатывают концентрированной серной КИСЛОТОЙ, а затем полученный раствор обезжелезивают, обрабатыва , например бисульфатом аммони . Однако этот способ сложен, так как требует использовани серной КИСЛОТЫ высокой концентрации.A known method of processing kaolin on alumina is that calcium is calcined at 560-580 ° C, treated with concentrated sulfuric acid, and then the resulting solution is deironed by treating, for example, with ammonium bisulfate. However, this method is difficult because it requires the use of high concentration of sulfuric acid.
С целью интенсификации процесса предлагаетс серную кислоту использовать в концентрации 12-20% и обезжелезивание вести дегидратированным алунитом.In order to intensify the process, it is proposed to use sulfuric acid in a concentration of 12–20% and deironing to lead dehydrated alunite.
Пример. Каолин обжигают при 600- 800°С в течение 1 час, а затем обрабатывают оборотным раствором, содержащим 15-20% серной КИСЛОТЫ, при 103-105°С также 1 час. Иульпу сгущают при 90-98°С, после чего провод т трехкратную противоточную промывку кремнеземистого щлама, который используют в строительных цел х. Сернокислый раствор обезжелезивают добавлением дегидратированного алунита в количестве примерно 10% от каолина.Example. Kaolin is burned at 600–800 ° C for 1 hour, and then treated with a circulating solution containing 15–20% sulfuric acid, at 103–105 ° C, also for 1 hour. The pulp is concentrated at 90-98 ° C, after which a threefold counter-current washing of the silica sand, which is used for construction purposes, is carried out. The sulphate solution is deironed by adding dehydrated alunite in an amount of about 10% of kaolin.
Извлечение глинозема из каолина составл ет 90-92%, из алунита 90-95%, извлечение серного ангидрида и щелочей составл ет 89-96%.The extraction of alumina from kaolin is 90-92%, from alunite 90-95%, the extraction of sulfuric anhydride and alkali is 89-96%.
