黄铜矿是所有铜矿物中较难浸出的矿物之一。利用氧化亚铁硫杆菌氧化浸出以黄铜矿为主的德兴铜矿原矿，当处理１ｋｇ矿石添加０１６和０３２ｇ银时，经过２１天浸出，铜的浸出率从未加银的２８２％分别提高到７７５％和７９７％。银的催化作用可能是通过改变矿物表面电化学性质，发生电化学反应而实现的。浸渣的Ｘ射线衍射结果表明，矿物表面有Ａｇ２Ｓ生成。通过育种方法可得到耐受银的质量浓度为１００ｍｇ／Ｌ的浸矿菌株。 Chalcopyrite is one of the more difficult minerals to leach out of all copper minerals. Leaching of chalcopyrite-based Dexing copper ore ore by using Thiobacillus ferrooxidans was used to leach copper in a rate of 016 and 032g when 1kg ore was treated. 28.2% increased to 77.5% and 79.7% respectively. Silver catalytic effect may be achieved by changing the electrochemical properties of the surface of the mineral electrochemical reaction. X-ray diffraction results of leaching residue showed that Ag2S was formed on the mineral surface. Through the breeding method can be tolerated silver concentration of 10  0mg / L leaching strains.
