  • Bioleaching and Electrochemical Behavior of Chalcopyrite

     · Recently bioleaching of another chalcopyrite sample using the strain YL15 at 6°C was performed and the highest copper leaching rate achieved was 19.3 (on day 80) (Zeng et al. 2020). It suggested that the difference in the mineral sample might result in significant contrast in the highest leaching rate and the leaching course.
