Abstract: A high-sulfur low-copper iron ore from Western Henan Province contains 0.33% Cu，9.84% S and 28.54% Fe，respectively.It belongs to the polymetallic ore with complex mineral composition and embedded relationship，uneven disseminated particle，and a high oxidation degree of copper and iron.Beneficiation study was carried out for determining the development and utilization program.The results showed that at the grinding fineness of -0.074 mm 85%，copper concentrate containing 20.62% Cu with a recovery of 64.98% and the sulphur concentrate containing 43.19% S with a recovery of 91.56% were obtained respectively by the process of copper and sulphur bulk flotation of one-roughing，three-cleaning and two-scavenging，Cu-S separation of one-roughing，three-cleaning and three-scavenging，and middles back to the flow-sheet in turn.Good concentration indexes were gained.The tailings from the bulk flotation contained 26.06% Fe with Fe recovery of 71.33% and the sulphur content in tailings was reduced to 0.68%，which provides good preconditions for the recovery of iron minerals.
