Abstract: In order to solve the impact of the tungsten slime on the flotation operation, after the ore is washed, the new asynchronous separation process of"scheelite flotation-wolframite magnetic rough separation-table cleaning"was developed for tungsten slime, that is, flotation and recovery of scheelite using a combination of high-speed shear mixing barrel+ cyclonic micro-bubble flotation column, the flotation tailings are pre-selected by high gradient magnetic separator and the table cleaning produces wolframite concentrate, the produced rough scheelite concentrate is feeds further in the original heating and cleaning process. The test results showe that when the feed ore grade is 0.96% WO₃, the grade of scheelite concentrate is 5.04% and the recovery is 71.80%; the grade of wolframite concentrate is 52.41% and the recovery is 20.86%, and the comprehensive recovery is 92.66%.
