MAXIMIZING THE EXTRACTION OF ALUMINUM AND ITS COMPOUNDS FROM ALUMINOSILICATES: LABORATORY AND INDUSTRIAL STUDIES

The sustainable development of inorganic chemical technology is closely associated with the efficient use of natural resources and the adoption of resource-saving processing methods for local mineral raw materials. This study focuses on the comprehensive processing of Uzbekistan’s aluminosilicate rocks—such as kaolin, bauxite, and zeolite—for aluminum extraction. The chloride decomposition method was investigated as an alternative to conventional acid and alkaline processes. Laboratory experiments were conducted to evaluate the effects of temperature, chloride concentration, and processing duration on aluminum extraction efficiency. The results demonstrate that chloride decomposition provides higher aluminum yields (up to 94%) with reduced energy consumption and environmental impact compared to sulfuric acid leaching. The findings are relevant for establishing low-waste, locally sourced production technologies, contributing to Uzbekistan’s industrial independence and environmental sustainability.
