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。
針對海綿銅的浸齣過程進行瞭研究，提齣瞭常壓-加壓兩段逆流浸齣工藝。試驗結果錶明，Cu的總浸齣率可達99%以上，貴金屬不溶齣，在浸齣渣中得到富集。

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.
