the effects of acidithiobacillus ferrooxidans and Fe3+ alone or in combination on the leaching rate of Mn2+ from MnO2 were studied. The catalysis of acidithiobacillus ferrooxidans and Fe3+ in the system was analyzed by the cyclic voltammetric method. Acidithiobacillus ferrooxidans and Fe3+ alone or in combination could effectively increase leaching rate of Mn2+
and have some catalytic effect on the bacterial leaching process of MnO2. Electrochemical analysis showed that acidithiobacillus ferrooxidans and Fe3+ alone or in combination could cause obvious redox peaks of FeS2
and acidithiobacillus ferrooxidans could reduce the oxidation potential of FeS2 and decrease the difference in potential between FeS2 oxidation peak and reduction peak
