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一浮选一弱磁选试验,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60min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.%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 ronghing-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.
