微生物浸出法回收硫酸渣中铜、锌的研究

Study on recovering Cu,Zn from pyrite cinder with bioleaching method

某硫酸厂硫酸渣中铜、锌含量较高,采用氧化亚铁硫杆菌浸出,铜、锌的浸出率达到91%以上,驯化菌种可进一步提高金属浸出率。

Pyrite cinder from one sulphuric acid plant contains copper and zinc. Copper and zinc could be bioleached from the pyrite cinder into liquid by using thiobacillus ferroxidants. The leaching ralio was over 91%. The leaching ratio could be made further improvement by using cultured bacteria.
