摘      要：Froth flotation is often used for fine-particle separation,but its process efficiency rapidly decreases with decreasing particle *** efficient separation of ultrafine particles(UFPs)has been a major challenge in the mineral processing field for many *** recent years,the use of surface nanobubbles in the flotation process has been recognized as an effective approach for enhancing the recovery of *** with traditional macrobubbles,nanobubbles possess unique surface and bulk characteristics,and their effects on the UFP flotation behavior have been a topic of intensive *** review article is focused on the studies on various unique characteristics of nanobubbles and their mechanisms of enhancing the UFP *** purpose of this article is to summarize the major achievements on the two topics and pinpoint future research needs for a better understanding of the fundamentals of surface nanobubble flotation and developing more feasible and efficient processes for fine and UFPs.
