Abstract: The mineral composition of a gold-bearing copper ore in China is complex，and the main recovered minerals are gold-silver minerals and copper minerals. In order to efficiently recover and utilize the ore，the beneficiation test is carried out on the basis of the study of ore properties.The results show that under the conditions of grinding fineness of -0.074 mm 90%，Na2CO3 dosage of 1 200 g/t，water glass dos⁃ age of 1 200 g/t，Na2S dosage of 600 g/t，total dosage of butyl xanthate of 160 g/t and roughing flotation time of 6 min，the open-circuit flotation process test of one roughing，two cleanings and two scavengings is car⁃ ried out，the concentrate with gold grade of 67.48 g/t，gold recovery of 47.88%，copper grade of 17.22% and copper recovery of 51.60% can be obtained.Due to the high gold content of flotation tailings，up to 0.69 g/t， other beneficiation methods can be considered to extract gold from flotation tailings in the future，so as to re⁃ alize the efficient recovery and utilization of valuable minerals in ore to a large extent.
