摘　　要：针对海绵铜的浸出过程进行了研究,提出了常压—加压两段逆流浸出工艺。试验结果表明,Cu的总浸出率可达99%以上,贵金属不溶出,在浸出渣中得到富集。This paper studied the leaching process of sponge copper. A new hydrometallurgical process-atmospheric and pressure countercurrent leaching was proposed. The test results showed that the leaching ratio of copper could reach 99%, noble metals were not leached and gathered in slag.

关 键 词：海绵铜 两段逆流 加压浸出
