Abstract: Plasma, a green and environmental friendly surface modification technology, has attracted more attention as its excellent properties, such as simple operation, rapid response, low energy consumption and dry process. In this paper, the producing method of plasma and its application in the field of mineral flotation were summarized, as well as the mechanism of its action on mineral and reagent modification in flotation, and the application of plasma in the mineral processing field was prospected. The review would provide a guidance for the popularization and application of plasma technology for efficient utilization of the mineral resources.
