Abstract: Aiming at copper flotation tailings containing WO₃ and according to the ore properties of a skarn scheelite from GanSu,this experiment studied the suitable conditions of flotation,whose results show that the original process using collector ZL's collecting ability is bad on fine tungsten ore.The experiment of the collectors(such as collector ZL,ZL+ LDZ,ZL+ GYB,GYB + LDZ) and inhibitor were studied respectively.Research results show that under the best dosage is 650g/t of the combination collector GYB:LDZ=2.5:2.5,the best dsage is 2.5kg/t of the inhibitor,we obtained the best flotation indexes.Rough concentrate grade is 1.24% but the recovery rate is 82.31%.
