研究了氧化亚铁硫杆菌对黄铜矿的浸出行为。在酸性介质中，黄铜矿被氧化成CuSO4和Fe2（SO4）3。加入0．4％的FeSO4·7H2O，加快了黄铜矿的最初浸出速率，更高的Fe2+浓度反而抑制最初浸出速率。加入Fe2（SO4）3使浸出速率增加。加入Fe2+和Fe3+使最终浸出率达到78．7％，而仅用细菌浸出的最终浸出率只有69％。通过研究细胞质酶对S2-的氧化，发现细胞色素C参与了S2-的氧化，从而间接证明了细菌对黄铜矿的直接作用。 The leaching behavior of Thiobacillus ferrooxidans to chalcopyrite was studied. In acidic media, chalcopyrite is oxidized to CuSO4 and Fe2 (SO4) 3. The addition of 0.4% FeSO4 · 7H2O accelerates the initial leaching rate of chalcopyrite, while the higher Fe2 + concentration suppresses the initial leaching rate. Addition of Fe2 (SO4) 3 increased the leaching rate. The final leaching rate reached 78.7% with the addition of Fe2 + and Fe3 +, whereas the final leaching rate with bacterial leaching alone was only 69%. By studying the oxidation of S2- by cytoplasmic enzymes, it was found that cytochrome C is involved in the oxidation of S2-, which indirectly proves the direct effect of bacteria on chalcopyrite.
