Research progress of micro-fine mineral carrier flotation technology
Due to the special physical and chemical properties of fine-grained minerals,the flotation efficiency of conventional beneficiation methods is low.Carrier flotation,as an effective flotation technology for fine-grained minerals,can significantly improve the flotation efficiency of fine-grained minerals by using suitable carriers.This paper first introduces the surface properties and flotation behavior of fine-grained minerals,as well as the basic principle of carrier flotation and the interaction mechanism between carrier and fine-grained minerals.Thereafter,the research and application status of micro-fine mineral carrier flotation are analyzed,and the influencing factors of carrier flotation are summarized.The characteristics,advantages,and disadvantages of the three kinds of flotation carriers,including similar carrier,heterogeneous carrier,and branch carrier are pointed out,and the future development trend of these carriers has been prospected,aiming to Provide a reference for further industrial application of carrier flotation.
