Abstract: The ores containing iron and copper in Anhui is a typical polymetallic associated ore， with close symbiosis among minerals and complex distribution.The metallic minerals in the ore are mainly magnetite， and a small amount of pyrite， chalcopyrite， pyrrhotite and so on. The non-metallic minerals are mainly serpentine， diopside， tremolite and so on.In order to comprehensively recover the valuable components in the ore， the process flow of copper-sulfur mixed floatation，copper-sulfur separation and magnetic separation of mixed tailings was adopted to treat the ores on the basis of the condition test. The copper concentrate with Cu grade of 22.18% and Cu recovery rate of 76.85%， sulfur concentrate with S grade of 43.29%，S recovery rate of 45.71%，Co grade of 0.43%， Co recovery rate of 45.04%，and iron concentrate with Fe grade of 62.36%，Fe recovery rate of 93.09%，S contents of 0.18% was finally obtained through the whole process test.The test indexes are good and the associated component Co effectively enriched in the sulfur concentrate，indicating the comprehensive recovery of the valuable metals.

Key words: polymetallic ore, combined flotation, magnetic separation, comprehensive recovery
