| 摘 要： | 采用浮选?浸出工艺处理含铜0.94%的玄武岩型氧化铜矿，该铜矿物氧化率高，嵌布粒度较细，属于低品位难选氧化铜。通过硫化浮选法回收部分氧化铜矿及硫化铜矿，可得到品位为16.2%，回收率为50.7%的浮选铜精矿，通过硫酸浸出法回收浮选尾矿中的细粒级铜矿物，浸出率达87%，此浮选-浸出工艺实现了铜矿物的有效回收。

| Abstract: | The basalt type oxidized copper ore containing 0.94% copper was treated by flotation-leaching process. The copper mineral has high oxidation rate and fine inlay size, so it belongs to low-grade refractory copper oxide. The flotation copper concentrate with grade of 16.2% and recovery rate of 50.7% can be obtained by recovering part of oxidized copper ore and sulfide copper ore by sulfurization flotation. The fine-grained copper mineral in flotation tailings can be recovered by sulfuric acid leaching, with the leaching rate of 87%. This flotation-leaching process realizes the effective recovery of copper mineral. |
