摘　　要：水玻璃是矿物浮选过程中一种常用的调整剂,但近年来矿石呈现出品位低、嵌布粒度细和组成复杂的特点,使用单一水玻璃作为调整剂难以实现选择性抑制,而对水玻璃进行改性可以实现低成本配制的同时大幅度增强水玻璃的选择性抑制效果。综述了金属离子和酸分别对水玻璃的改性方法,探讨了铝盐改性水玻璃、铁盐改性水玻璃和铅盐改性水玻璃等多种盐化水玻璃,以及硫酸酸化水玻璃和草酸酸化水玻璃在浮选中的应用现状和抑制机理,展望了未来改性水玻璃的发展方向,为高性能改性水玻璃的研发以及改性水玻璃在矿石高效分选中的应用提供参考。Water glass is a commonly used regulator in mineral flotation processes,but it is difficult to achieve selective inhibition because of the characteristics of low grade,fine embedded particle size,and complex composition for minerals.However,modifying water glass can enhance the selective inhibition effect and save costs.This article reviews the modification methods of water glass by metal ions and acids,and the application and inhibition mechanism of various types of salted water glass such as aluminum salt modified water glass,iron salt modified water glass,and lead salt modified water glass,as well as sulfuric acid acidified water glass and oxalic acid acidified water glass in flotation.It also looks forward to the development direction of future modified water glass,and provides a reference for the development of high−performance modified water glass and its application.
