　　The alternating current impedance analysis was used to study the relationships between anodic potential and time for bio-electro-generative simultaneous leaching (BEGL) of pyrite and the interface dynamic behaviors of pyrite carbon paste electrodes in the presence ofAcidithiobacillusferrooxidans (A.ferrooxidans).A simulated equivalent circuit of BEGL process for pyrite was constructed.Using the software Z-View2, Nyquist diagrams of pyrite anode at different initial electric potential were fitted and analyzed.
