氧化预处理技术在铜钼硫化矿浮选分离中的研究进展

Research Progress of Oxidation Pretreatment Technology in the Flotation Separation of Copper-molybdenum Sulphide Minerals

黄铜矿和辉钼矿是两种典型的硫化矿,其浮选分离一直是业界关注的焦点。硫化矿易氧化,矿物表面氧化程度和氧化产物类型对其浮选行为有重要影响。黄铜矿、辉钼矿在浮选之前进行氧化预处理,它们会产生不同程度的氧化和不同类型的氧化产物,这些原因使矿物的表面原有的性质发生改变,从而改变矿物固有的浮选行为,实现黄铜矿和辉钼矿的浮选分离。论文介绍了黄铜矿、辉钼矿的表面特性,分析了其表面氧化机理,综述了铜钼硫化矿氧化浮选分离的研究现状,旨在为铜钼硫化矿物绿色、高效浮选分离提供一定的借鉴。

Chalcopyrite and molybdenite are two typical sulfide minerals,and their flotation separation has always been the focus of the industry.Sulfide minerals are easy to be oxidized,and the degree of mineral surface oxidation and the type of oxidation products have important influences on their flotation behavior.Chalcopyrite and molybdenite undergo oxidation pretreatment before flotation,which will produce different degrees of oxidation and different types of oxidation products.These reasons change the original properties of the mineral surface,so as to change the inherent flotation behavior of minerals and realize the flotation separation of chalcopyrite and molybdenite.This paper introduces the surface characteristics of chalcopyrite and molybdenite,analyzes their surface oxidation mechanism,and summarizes the research status of oxidative flotation separation of copper molybdenum sulfide minerals,in order to provide some reference for green and efficient flotation separation of copper-molybdenum sulfide minerals.
