The Zunyi region is rich in high-sulfur bauxite, but the high sulfur content significantly affects the quality and subsequent processing and utilization of the bauxite. To enhance the desulfurization efficiency of flotation, an optimization study was conducted on the desulfurization process. The study analyzed the issues in the current process regarding reagents, flotation equipment, and procedures. By optimizing the collector and adjusting the reagent ratios, improving the flotation equipment, and restructuring the flotation process, the sulfur content in the concentrate was significantly reduced, and the aluminum recovery rate was notably increased. After optimization, the sulfur content in the concentrate was significantly reduced, and the aluminum recovery rate was notably increased, achieving efficient desulfurization and comprehensive resource utilization of high-sulfur bauxite, providing technical support for the development of bauxite in the Zunyi region.
