Abstract: The WO3 grade in a skarn scheelite in Xizang province is 0.52% and the gallium content is 19.08 g/t. The scheelite is of coarse grain size and belongs to medium-coarse grain dissemination. In order to develop a reasonable beneficiation process， representative ore samples were selected for beneficiation process tests， and the recovery process of associated element gallium was explored using leaching process. The test results showed that: ① under the condition of grinding fineness of -0.074 mm accounting for 75.0%， sodium silicate as inhibitor， 733 as collector and sodium carbonate as regulator， tungsten coarse concentrate with WO3 grade of 12.34% and WO3 recovery rate of 64.91% was obtained through the closed-circuit test of one roughing， two cleaning and two scavenging. ② Tungsten concentrate with WO3 grade of 66.20% and WO3 recovery rate of 95.12% was obtained through the closed-circuit test process of tungsten warming cleaning with coarse tungsten coarse concentrate as feeding ore. ③ The optimal leaching conditions of gallium as a associated element are as follows: stirring temperature of 90 ℃， H2SO4 dosage of 350 g/L， leaching time of 6 h， leach aid agent CaF2 dosage of 2.5 g， liquid-solid ratio of 8∶1， stirring speed of 300 r/min. The leaching rate of gallium is 62.55% in the best condition.
