Разработка технологии получения высокочистых порошков AL2O3 на основе сырья Уральского региона

This article is devoted to the integrated use of technogenic and natural aluminous raw materials in order to extract valuable components while solving environmental problems. The analysis of the granulation process of kaolin in the Ural region with the addition of an aqueous solution of sulfuric acid and subsequent firing of granules is carried out. Sulfuric acid leaching of kaolin-containing raw materials at various acid concentrations and the duration of the precipitate was considered. The obtained aluminum hydroxide powders were certified.
