potential is much higher than the proposed appropriate range (380-480 mV vs Ag/AgCl) with the solid waste added. There is a positive correlation between temperature and copper extraction rate. The kinetics..., bioleaching process gets lots of advantages [1-8]. However, the application of bioleaching has been hindered for its slow kinetics and low extraction rate. Chalcopyrite (CuFeS2) is the most widespread......
