Abstract:Flotation equipment is the core equipment for flotation processing and plays an important role in the efficient recovery of mineral resources. With the exploitation of mineral resources，the ore is increasingly depleted，and the size of mineral particles has an increasingly significant impact during processing. This article takes mineral particle size as the main line，and summarizes and analyzes the research progress in conventional，coarse，and fine particle flotation equipment and their intelligence from three levels：basic theory，key technologies，and industrial applications. Overall，with the increasing demand for mineral resources and the demand for green，low-carbon，and intelligent development of mineral processing plants，the development of flotation equipment is unprecedentedly prosperous and in a new stage of historical development.
