Abstract: Quartz-calcite type scheelite is usually gravity separated and the result is not ideal.After the researching and analysis of the process, some experiments have been carried out by flotation dressing and a series of process parameters have been tested.Finally, ideal process parameters of flotation dressing have been achieved and copper and tungsten could be obtained.Concentrate of scheelite grade reaches 68.65% of WO₃ and WO₃ recovery is 84.75%.
