Abstract

Bauxite, a primary raw material for alumina production, has its silicon content significantly impacting subsequent processing and product quality. As high-quality bauxite resources become increasingly scarce, the development of efficient silicon-removal technologies has become a focal point in the industry. This paper focuses on the applicability of new efficient silicon-removing agents in bauxite pretreatment, using a series of experiments and analytical methods to explore their effectiveness under various conditions. The study examines the interaction mechanisms between the agents and the mineral components in bauxite, the key factors influencing the silicon-removal process, and their practical performance. The results indicate that the new agents exhibit outstanding silicon-removal performance under specific conditions, significantly enhancing the aluminum-to-silicon ratio of bauxite. This improvement provides higher-quality raw materials for alumina production, potentially driving innovation in bauxite pretreatment technology and promoting the sustainable development of the alumina industry.
