Abstract: A Henan magnetite ore contains also copper and sulfur minerals, with a considerable amount of sulfur minerals being pyrite. Test research was made on this ore for the industrial evaluation of the related deposit and the ore beneficiability. The results show that a combined process of sequential flotation of copper and sulfur and low intensity magnetic separation of flotation tailings can recover in a comprehensive way the copper, sulfur and iron from the ore, with the iron concentrate grading 65.10% at a recovery of 57.23%, sulfur concentrate grading 42.00% at a recovery of 95.62% and copper concentrate grading 19.20% at a recovery of 52.79%, The iron concentrate contains 0.03% copper and 0.25% sulfur, which satisfy the state standard for the impurity content in Class 2 iron powder concentrate.
