Abstract: Process mineralogy research on representative samples of the tungsten ore was carried out in order to explore a reasonable exploitation and utilization scheme.The result indicated that the valuable elements of the ore include wolfram，molybdenum and copper and their corresponding valuable minerals are scheelite，molybdenite and chalcopyrite respectively.The valuable minerals are complexly and finely disseminated with each other.The scheelite is finely and evenly disseminated，while chalcopyrite and molybdenite are micro-finely and unevenly disseminated.The grade of WO₃ in scheelite reached 74.76% and 95.30% of wolfram exist in scheelite.The grade of molybdenum in molybdenite and scheelite was 57.84% and 2.83% respectively.And 58.25% of molybdenum exists in molybdenite and 33.20% of molybdenum existed in scheelite.The copper grade in chalcopyrite is 31.24% and 87.92% of copper exists in chalcopyrite.The scheelite is easier to be liberated，followed by molybdenite，while chalcopyrite is the hardest.The liberation degree of scheelite，chalcopyrite and molybdenite were 97.48%，89.20 and 91.67% respectively at the grinding fineness of 65.81% passing -0.074 mm.
