Abstract: In light of the ROM ore properties, a technological flowsheet was proposed and tested that consisted of preferential flotation of sulfide ore, bulk flotation of  wolframite and scheelite, heating cleaning for scheelite recovery and gravity separation of the cleaning tailing for wolframite recovery. As a result, from a feed containing WO₃ 0.81%, a scheelite concentrate grading 65.99% WO₃at a recovery of 60.55%; a wolframite concentrate grading 65.4% WO₃ at a recovery of 13.78%; and a sub-scheelite concentrate grading 30.2% WO₃ at a recovery of 10.45% were obtained, with the total WO₃ recovery being 84.78%, a good metallurgical performance.
