Abstract: In order to recover the scheelite from molybdenum tailings, adopted the process of  pre-classification-+0.15 mm coarse fraction regrinding-one roughing one scavenging flotation desulfurization-one roughing one scavenging one cleaning flotation scheelite under normal temperature-one roughing three scavenging five cleaning heating flotation scheelite, got the tungsten concentrate with grade of WO₃ at 60.14%, recovery of WO₃ at 77.78%. Coarse fraction regrinding avoids the production of slime and over crushing of scheelite, adding the LY inhibitor can inhibit the gangue containing calcium. These measures ensure the test get better indexes.
