摘要
黄铁矿是一种广泛存在的硫化金属矿,其浮选问题一直是矿业工程领域的研究热点。浮选实践表明不同成因黄铁矿间可浮性存在差异性,主要由其矿物学因素差异所致。黄铁矿矿物学因素的微小变化会对其浮选行为产生不同程度的影响,如晶格缺陷会通过改变黄铁矿矿物表面吸附特性来增强或降低其可浮性。主要分析了晶格缺陷、物理性质和化学组成三方面因素对黄铁矿可浮性的影响,论述了矿物学因素与黄铁矿浮游特性间的普遍规律性,以引起选矿工作者对矿物学因素的重视,为黄铁矿浮选实践提供理论参考。
Pyrite is a widely-existing metal sulfide ore,and its flotation problem has always been a research hot spot in the field of mining engineering.Flotation practice shows that there are differences in floatability between pyrites of different genesis,mainly due to differences in mineralogical factors.Small changes in the mineralogical factors of pyrite may have different effects on their flotation behavior.For example,the pyrite lattice defects will enhance or reduce the floatability by changing the adsorption characteristics of the mineral surface.In this paper,the effects of lattice defects,physical properties and chemical composition on the floatability of pyrite are analyzed and the general regularity between mineralogical factors and the floating characteristics of pyrite is discussed.The purpose of this paper is to cause the mineral processing workers to pay attention to mineralogy factors and provide a theoretical reference for the practice of pyrite flotation.
