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.
