摘　　要：某铜矿含铜1.07%,氧化程度高、嵌布粒度细、含泥高,属低品位复杂难选氧化铜矿。针对该矿石的特点,探索了不同的解决方案。最终小型闭路试验获得了铜品位为21.52%、铜回收率为78.66%的铜精矿。A refractory copper ore contains 1.07% Cu and to some extent it is oxidized,the valuable minerals are fine disseminated and with high extent slimes in the ore.Based on the characteristics of the copper ore,different solutions were explored.Finally copper concentrate grading 21.52% Cu with recovery of 78.66% was obtained by the small-scale closed-circuit test.
