摘要：

The mineral processing flow sheet and reagent system of flotation copper minerals from a large copper-iron deposit in Yunnan were fully investigated. The results indicate that the optimum conditions for flotation of copper minerals from the material were identified as grinding fineness of 85%, dosage of CaO at 2000g/t, dosage of Na2S at 200 g/t, dosage of butyl xanthate 40g/t. Under such a condition, a copper recovery of 88.17% with a concentrate grade of 26.86% was achieved from the material using a closed circuit flow sheet of "one-stage roughing flotation, one-stage cleaning flotation and one-stage scavenging flotation.
