摘要/Abstract

摘要： 云南某铜矿石属典型的低品位、高氧化率硫氧混合型铜矿石，含铜033%，其中硫化铜占有率为4909%，氧化铜占有率为5091%。为确定该矿石的开发利用工艺，进行了选矿试验研究。结果表明，在磨矿细度为-0074 mm占8640%的情况下，采用1粗3精1扫流程浮选硫化铜矿物、1粗3精1扫流程浮选氧化铜矿物，可获得铜品位1858%、回收率7755%、金品位423 g/t的铜精矿。试验指标良好，实现了低品位硫氧混合型铜矿石中铜、金的高效综合回收，可作为该矿石开发利用工艺设计的依据。

Abstract: A lowgrade and highoxidation rate of mixed sulphideoxide copper ore in Yunan Province contains Cu content of 0.33%,copper sulphide of 49.09% and copper oxide of 50.91%.In order to determine the development and utilization technology of the ore,the mineral processing testing studies were carried out.The results presented that in the case where the grinding fineness is -0.074 mm accounting for 86.40%,the copper concentrate with copper content of 18.58%,recovery rate of 77.55% and gold content of 4.23 g/t can be obtained by using a copper sulfide flotation process and a copper oxide flotation process with both one stage of roughingthree stages of cleaningone stage of scavenging procedures.The indexes of test results performed well,and the study realized an efficient comprehensive recovery of copper and gold in lowgrade mixed sulphideoxide copper ore,which could provide the technological design basis for the mine development and ore utilization.
