遵义地区高硫铝土矿浮选脱硫工艺优化研究

摘要

遵义地区高硫铝土矿储量丰富，但硫含量高严重影响铝土矿质量与后续加工利用。为提升浮选脱硫效率，对其浮选脱硫工艺进行优化研究。深入分析现有工艺在药剂制度、浮选设备与流程方面存在的问题，通过优化捕收剂、调整剂配比，改进浮选设备，重构浮选流程，大幅降低精矿硫含量，提高铝回收率。经优化，精矿硫含量显著下降，铝回收率明显提升，实现了高硫铝土矿高效脱硫与资源综合利用，为遵义地区铝土矿开发提供技术支撑。

Abstract

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.
