摘    要：

某矿山入选矿石中矿物次生硫化富集作用明显，适宜现场“快速优先-铜硫混浮，中矿可选择性再磨铜硫分离”选矿新工艺生产流程，闭路试验结果为铜精矿品位25.38%，选铜回收率82.42%，硫精矿品位31.64%,选硫回收率60.59%．

Abstract: The secondary sulfur enrichment being the striking features of the mineral ore to be processed, a new dressing technology including faster precedence , copper-sulphur mixed flotation, and selective re-grinded copper-sulphur separation out of middlings, is adopted. The following are the closed-circuit test results: copper concentrate grade is 25.38%; copper recovery rate is 82.42%;sulfur concentrate grade is 31.64%; sulphur recovery rate is 60.59%.
