Abstract: In light of the properties of the run-of-mine ore, a beneficiation process of molybdenite and bismuthinite bulk flotation- molybdenite and bismuthinite separation-wolframite recovery from tailings was tested.As a result, from a feed containing Mo 0.24%, Bi 0.10% and WO3 0.052%, the following products were obtained, including a molybdenite concentrate grading 52.43%Mo at a recovery of 92.15%, a bismuthinite concentrate grading 37.09% Bi at a recovery of 75.60%, and sub-bismuthinite concentrate grading 1.85%Bi at a recovery of 12.16%, with a total Bi recovery of 87.76%; and a wolframite concentrate grading 65.24%WO3 at a recovery of 58.22%, achieving a good recovery of Mo, Bi and WO3.
