Abstract: In order to provide the basis for the development of No.Ⅰore-body of Tibet Yulong Copper Mine,beneficiation tests on the mixed ore from each ore belt at this deposit are carried out. Aiming at the feature of copper associated with molybdenum in the ore,among which copper exists in form of copper sulfide and oxidized copper,and molybdenum mainly exists in form of molybdenum sulfide,total copper concentrate with Cu grade of 18.13% and Cu recovery of 79.31%,and molybdenum concentrate with Mo grade of 45.97%,and Mo recovery of 79.39% were finally gained by the process of bulk flotation of copper sulfide and molybdenum sulfide-separating flotation,bulk flotation of tailings and then the flotation of copper oxide.

Key words: No.Ⅰ Orebody of Yulong Copper Mine, Mixed ore, Bulk flotation of copper sulfide and molybdenum sulfide, Separating flotation of copper sulfide and molybdenum sulfide, Oxidized copper floatation
