英文摘要 | The beneficial effects of Acidithiobacillus ferrooxidans and/or Fe(III) on manganese bioleaching from a low-grade manganese ore were confirmed. The results showed that the rate of manganese bioleaching increases with the amount of A. ferrooxidans and/or Fe(III). With the presence of Fe(III) and A. ferrooxidans the average initial leaching rate increased from 0.06 to 0.15 g/(L h). Cyclic voltammetry analysis showed that the presence of A. ferrooxidans and/or Fe(III) generate obvious redox potential polarization in the solution. Fe(III) reduced the potential difference between anode and cathode of pyrite and promoted the positive cathodic polarization of pyrolusite at 0.2 V. In the process of pyrite oxidation A. ferrooxidans accelerated the generation and transfer of electron. |
