萤石与方解石、重晶石等盐类矿物浮选分离现状

Study on Flotation Separation for Fluorite and Salt Minerals of Calcite and Barite

简要介绍了我国萤石矿资源特点,并分析了其浮选分离困难的原因。概述了萤石矿捕收剂的研究现状及发展方向,对脂肪酸类捕收剂进行化学或生物改性及组合用药是提高药剂选择性的有效方法。同时对萤石与方解石、重晶石浮选分离的抑制剂研究现状及作用机理进行了阐述,在适宜的矿浆pH值条件下,多种无机或有机抑制剂组合使用,能够实现萤石与方解石、重晶石的浮选分离。

This paper introduced the characteristics of fluorite resources in our country, and pointed out the causes existing in the difficulty of flotation separation. Summarized the research status and the direction development of fluorite ore collector, and found out chemical or biological modification and combined reagents was an effective method on improving selectivity of fatty acid collector. Introduced the research status and depressing mechanism of fluorite ore inhibitors for fluorite with calcite and barite, and under the condition of appropriate slurry pH, a variety of inorganic or organic inhibitors combination, realized fluorite and calcite, barite flotation separation.
