Abstract: It is always a focus to improve the selectivity of collector and strengthen the efficiency of depressor in the study of scheelite flotation. The type of scheelite collector and adjustment, mechanism and research status are analyzed and reported, and it is put forward that the high selective collector and pertinence of inhibitory is an urgent problem needing to be solved in the scheelite flotation. It has become the development trend of white tungsten flotation reagents that using new and high technology and combining with the theoretical research to develop efficient, economic and environmental protective flotation reagents.
