摘要: 四川西部地区某含铜铁矿石中铁主要以鲕状赤铁矿形式存在,铜主要以结合氧化铜形式存在。对该矿石进行了氯化离析—浮选—弱磁选试验,结果表明:将矿石在氯化钠和焦炭用量均为7%、离析温度为950 ℃、离析时间为60 min的条件下进行氯化离析焙烧后,经1粗2精3次浮选,可以得到铜品位为19.64%、铜回收率为82.41%的铜精矿,浮选尾矿经1次弱磁选,可以得到铁品位为65.86%、铁回收率为78.62%的铁精矿。

Abstract: Iron minerals in a copper-iron ore in the region of western Sichuan mainly exists in form of oolitic hematite,and copper is mainly associated with copper oxide, so the process of chlorination segregation -flotation-low intensity magnetic separation was adopted for this ore. The results showed that under conditions of sodium chloride and coke dosage of 7% respectively, segregation temperature at 950 ℃ for 60 min, following by chlorination segregation and roasting, copper concentrate with Cu grade of 19.64%, and Fe recovery of 82.41% were obtained by the process of one roughing-two cleaning flotation. Then for tailings, iron concentrate with Fe grade of 65.86%, and Fe recovery of 78.62% were obtained by one low intensity magnetic separation.
