Institute of General and Inorganic Chemistry of Academy of Sciences of the Republic of UzbekistanAbstract
This article provides an in-depth study of the chemical and mineralogical composition of kaolin raw material from the Karnab deposit, its industrial applications, and beneficiation methods. The article describes effective techniques for removing harmful impurities present in Karnab kaolin, such as iron and titanium oxides, as well as alkali and alkaline earth metal oxides. The kaolin is bleached and its physical and optical properties are improved through the use of various chemical reagents (e.g., sulfuric, hydrochloric, and organic acids), flotation, hydrothermal, and autoclave processing technologies.
