Abstract: Detailed beneficiation test research was conducted on a copper tailings from Australia, and then a combined flowsheet of flotation-magnetic separation was adopted for comprehensive recovery of sulfur and iron in tailings. The result showed that new-type XT-01 as the collector for pyrite, a sulfur concentrate with the sulfur grade of 49.80% and recovery of 92.58% can be obtained. After flotation, the magnetic separation test which used wet low intensity magnetic separator has been done on flotation tailings, an iron concentrate with the iron grade of 64.11% and the total iron recovery of 45.91% was obtained. Comprehensive recovery and utilization of sulfur and iron in copper tailings was realized.
