Research Progress on Flotation Desilication for Bauxite

摘要: 面对氧化铝生产原料铝硅比日益降低的现状，低品位铝土矿的开发利用成为了铝土矿选矿的主要研究方向。本文从铝土矿正反浮选脱硅两个方面介绍相关的脱硅工艺，并对主要脱硅药剂的作用机理、性能特点、应用现状、发展趋势和研究方向进行了总结归纳，最后分析了目前铝土矿脱硅技术存在的主要难题并对其未来研究方向进行展望。

Abstract: With the depletion of high quality bauxite raw ore, the exploitation of bauxite with low aluminum-silicon ratio become a main research direction. The desilication techniques employed in bauxite beneficiation with direct and reverse flotation approaches were systematically elucidated. The main desilication reagents were comprehensively summarized in aspects of their function mechanisms, performance characteristics, application and research prospects. Furthermore, critical challenges in bauxite desilication technology were reported and potential future development was proposed.
