摘要：某复杂铜硫矿属于多金属铜硫矿石，铜品位为0.38%，硫品位为11.6%，品位较低，复杂难选。通过开展选铜捕收剂种类、磨矿细度、药剂用量、石灰用量、浮选时间以及选硫活化剂硫酸用量、捕收剂丁黄药用量等条件试验，采用优先浮铜工艺实现了铜硫矿石的有效分离。试验表明：铜优先浮选经一粗二精二扫，选硫经一粗二精一扫的闭路试验流程，可获得铜精矿铜品位20.88%，回收率93.69%，硫精矿硫品位46.0%，回收率89.48%的指标。

Abstract: A complicated copper sulfur ore belongs to the Polymetallic Copper Sulfur ore, copper grade is 0.38%, sulfur grade is 11. 6% ,its grade is low, complex and difficult to choose. Through the development of copper collector type, grinding fineness, dosage, lime dosage, flotation time and flotation activator dosage of sulfuric acid, butyl xanthate collector dosage test,the effective separation of copper and sulfur ores was achieved by using the preferential flotation copper technology. The test shows that after the closed flotation process of one roughing, two cleaning, two scavenging for copper flotation and one roughing, two cleaning, one scavenging for sulfur flotation, the copper concentrate with grade of 20.88% and recovery of 93. 69% and the sulfur concentrate with grade of 46% and recovery of 89.48% were obtained.

0引言
铜矿石是我国经济发展中不可或缺的金属矿石，随着矿石的日益开采，矿产资源日趋减少，优质矿石的数量急剧下降。开采的大多数矿石铜品位极低，给铜矿物的分选增加了大量困难。我国生产的铜矿主要来源于黄铜矿，黄铜矿是一种铜铁硫化矿物，常伴有微量的金、银等。铜硫矿石的浮选是

获取铜金属的重要加工环节，其过程主要是将硫化铜矿物与硫化铁矿物及脉右进行分离，因此，铜硫分流是铜硫矿物浮选过程中的关键技术。
