摘　　要：云南某铜矿含铜0.86%,矿石中铜的氧化率78.89%,且矿石中难选赤铜矿的含量高。根据矿石特点,试验采用简单的硫化铜、氧化铜混合浮选工艺,以硫化钠及乙二胺磷酸盐为活化剂,得到铜品位为24.03%,回收率为56.37%的铜精矿。A copper ore with high content of cuprite which is difficult to be beneficiated from Yunnan province contains 0. 86% of copper, and its oxidization rate of copper is 78.89%. Based on the characteristics of the ore, the simple process of bulk flotation of sulphide and oxidized copper minerals has been adopted in beneficiation tests and a copper concentrate of 24. 03% Cu with recovery of 56. 37% has been obtained.
