Abstract: The scheelite ore in Xinjiang has a complex mineral composition，WO₃ content is 0.772% and 95.85% of tungsten exists in form of scheelite，other metallic minerals are mainly galena，sphalerite，pyrite，etc.Scheelite are irregularly distributed in the gangue minerals，most of which are fine，and some are irregular short strips and irregular aggregate.Beneficiation process was studied based on the process mineralogy analysis to realize highly efficient recovery of tungsten.The results indicated that，scheelite concentrate with WO3 grade of 66.38% and recovery of 83.40% was obtained by adopting the process of one roughing and one scavenging to remove sulphide，one roughing and one scavenging for floating scheelite at room temperature，three cleaning for floating scheelite by heating at the grinding fineness of -0.074 mm accounted for 60%.
