Abstract: Flotation separation of scheelite from calcium gangue minerals was one of the difficulties in mineral processing industry.The perspective of solution chemistry indicated that transformation of mineral surface changed chemical composition，surface electrical and floatability of minerals，which is the main reason for difficulty in flotation separation of scheelite from fluorite and calcite.The regular flotation collectors and depressors of scheelite were summarized；the types，properties and action mechanism of new type of efficient collectors and depressors for flotation separation between scheelite and calcium gangue minerals at room temperature were introduced.Moreover，the advantage of combined collector and combined depressor in the process of flotation practice of scheelite was illustrated.It is pointed out that efficient collectors and depressors will be the research direction in the future.

Key words: Scheelite, Calcium gangue, Flotation separation, Collector, Depressor
