Abstract
1. Способ получения глинозема, включающий обработку алюминийсодержащего сырья соляной кислотой, кристаллизацию гексагидрата хлорида алюминия из осветленного хлоридного раствора, двухстадийное термическое разложение гексагидрата хлорида алюминия с получением глинозема и термогидролиз маточного раствора с выделением гематита, отличающийся тем, что первую стадию термического разложения гексагидрата хлорида алюминия ведут до образования оксихлоридов и аморфного гидроксида алюминия, часть их порционно вводят в осветленный раствор перед кристаллизацией гексагидрата хлорида алюминия до достижения рН, равного 1,6-2,2, образовавшийся при этом осадок гидроксида железа отделяют и смешивают с маточным раствором.2. Способ по п.1, отличающийся тем, что часть полученного гематита возвращают в осветленный раствор после достижения рН, равного 1,6-2,2.1. A method for producing alumina, including treatment of aluminum-containing raw materials with hydrochloric acid, crystallization of aluminum chloride hexahydrate from a clarified chloride solution, two-stage thermal decomposition of aluminum chloride hexahydrate to obtain alumina and thermal hydrolysis of the mother liquor with the release of hematite, characterized in that the first stage of thermal decomposition of aluminum chloride hexahydrate lead to the formation of oxychlorides and amorphous aluminum hydroxide, some of them are portionwise introduced into the clarified solution before the crystallization of aluminum chloride hexahydrate until a pH of 1.6-2.2 is reached, the precipitate of iron hydroxide formed in this case is separated and mixed with the mother liquor. The method according to claim 1, characterized in that part of the resulting hematite is returned to the clarified solution after reaching a pH of 1.6-2.2.
