Research Status and Prospect of Flotation of Fine Scheelite

As tungsten resources are being exploited in great quantities, scheelite resources are becoming increasingly "depleted, scattered, and fine". This has brought more attention to the recovery and utilization of micro-fine scheelite. The difficulties encountered in micro-fine scheelite flotation was analyzed, and the research progress on the flotation processes, flotation reagents, and flotation equipments were reviewed. Furthermore, the effects of bubbles, grinding, and the interaction of different particle sizes on fine scheelite flotation were revealed, and the future research focus for fine scheelite flotation was prospected. The review could provide a valuable reference for the flotation and efficient recovery of micro-fine scheelite resources.
