有价金属的回收利用，为高效开发利用该矿石提供了依据。
The copper content of a copper-bearing pyrite in Jiangxi is 1.33%，of which copper oxide accounts for 15.79% and sulfur content is 32.24%. In order to develop and utilize the ore，a closed-circuit test was carried out with lime as pH regulator，APII as copper collector and butyl xanthate as sulfur collector under the grinding fineness of -0.074 mm accounting for 70%. The flotation indexes of copper concentrate with copper grade of 17.97%，copper recovery of 72.21%，gold grade of 4.69 g/t，silver grade of 160.53 g/t and sulfur concentrate with sulfur grade of 48.93% and sulfur recovery of 89.05% were obtained. The recov⁃ery and utilization of valuable metals in the ore are realized，which provides a basis for the efficient develop⁃ment and utilization of the ore.
