方解石与共伴生矿物浮选交互影响研究进展

Research Progress on Mineral Interaction in Flotation System Composed of Calcite and Its Associated Minerals

方解石与共伴生矿物常通过浮选方法分离,其分选效果取决于浮选药剂性能和矿物表面性质差异。然而,混合矿体系中矿物颗粒间存在交互作用,如异相凝聚或溶解组分吸附、迁移、反应等,影响高效浮选药剂选择性吸附和矿物间表面性质差异,是高效浮选药剂在实际矿石分选体系中失去选择性的一个重要原因,也是复杂矿石难以分选的一个重要因素。归纳综述了氧化物矿物、碳酸盐矿物和含钙盐类矿物与方解石浮选分离过程中的交互影响机制及调控方法,分析了含有方解石体系的矿物交互影响研究现状与发展趋势,为方解石与共伴生矿物高效浮选分离研究提供借鉴。

Flotation is often used to separate valuable minerals from calcite.The flotation reagents and surface properties difference determines the flotation separation efficiency of calcite and its associated minerals.However,the interaction of minerals particles,as well as the adsorption and chemical reaction of soluble component with other minerals,change the surface properties and selectivity performance of flotation reagents.Minerals interactive effect is an important factor that makes it difficult to separate complex ores,and also an important reason for the loss of selectivity of high efficiency flotation reagent in mixed minerals or actual ores system.In this paper,the interaction mechanism and regulation methods of oxidation minerals,carbonate minerals and calcium salt minerals with calcite were summarized,and the research status and development trend of mineral interaction were preliminary clarified,so as to provide reference for further research of mineral interactive effect.
