Abstract: With the depletion of coarse−grained ore resources, ultrafine mineral resources are gradually becoming the primary focus of mineral resource development and utilization. Based on the challenges in flotation separation of ultrafine minerals, this paper systematically summarized the current research status of flotation equipment for ultrafine minerals, including the aerated flotation column, the cyclonic−static microbubble flotation column, and the EFD cavity resonant flotation column. Furthermore, from the perspective of flow field regulation, this paper systematically elaborated on various flow field control methods, including mechanical agitation flow field control, jet flow field control, and coupled mechanical agitation−jet flow field control, among others. Finally, the roles, existing challenges, and future directions of these flow field control methods in ultrafine mineral flotation were analyzed. This aims to provide reference and insights for the advancement of ultrafine mineral flotation equipment and flow field control technologies.
