Tin is a strategic metal in China,but the contradiction between supply and demand is prominent.Cassiterite has the characteristics of"brittle and fragile,easy to mud".How to realize the efficient recovery of ultrafine cassiterite has always been a research hotspot and difficulty.In this paper,the research progress of ultrafine cassiterite flotation process and flotation reagents was reviewed.Traceability analysis of the inevitable ions in the process of cassiterite flotation was carried out.The influence of different metal ion systems on the flotation behavior of cassiterite was systematically analyzed from the aspects of cassiterite mineral surface and reagent structure.Finally,the development direction of ultrafine cassiterite flotation in the future was predicted from the factors of tin slime flotation process,reagent properties,safety and environmental protection,flotation equipment.
