Abstract: By low intensity magnetic separation-wolframite and scheelite mixed flotation- wolframite and scheelite separation flotation-scheelite cleaning flotation-wolframite shaking table gravity separation-wolfframite fine mud flotation process for tungsten separation from tungsten,molybdenum,bismuth,fluorite complex polymetallic ore of sulphide flotation tailings,scheelite concentrate can be obtained by 68.79% WO3,the recovery rate of 53.27%,wolframite tungsten concentrate with WO3 grade of 52.49%,the recovery rate of 17.57%,the total tungsten recovery rate of 70.84% technology indicators was obtained.It is also pointed out that acid leaching of scheelite concentrate can remove phosphorus and remove calcite and other impurities,and the grade of scheelite concentrate increased by 2.46 percentage points.
