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.无机化工技术的可持续发展，与自然资源的高效利用以及针对本地矿物原料采用资源节约型加工工艺紧密相关。本研究聚焦于乌兹别克斯坦境内铝硅酸盐矿石的综合加工以提取金属铝，涉及的矿石品类包括高岭土（kaolin）、铝土矿（bauxite）以及沸石（zeolite）。研究选取氯化物分解法作为传统酸法、碱法工艺的替代方案开展探究。通过实验室实验，系统评估了温度、氯化物浓度与加工时长对铝提取效率的影响。实验结果表明，相较于硫酸浸出（sulfuric acid leaching）法，氯化物分解法可获得更高的铝提取率（最高可达94%），同时能耗更低、对环境的负面影响更小。本研究成果可为构建低废弃物、依托本地原料的生产技术体系提供支撑，助力乌兹别克斯坦实现工业自主与环境可持续发展。
