Abstract: In this paper, the collecting property of a new type of chelating reagent F-305 to Wolframite and Scheelite was studied by the single mineral experiment and actual-mineral-experiment.The test results showed that compared with conventional reagent 733 oxyparaffin soap of wolframium mineral, F-305 had a very strong collecting power for wolframium minerals, especially for Wolframite, and could get good flotation index at normal temperature.The Collection Mechanism was analyzed by Infrared Spectrum.

Key words: Scheelite, Wolframite, F-305
