| Abstract: | The leaching behavior of low grade copper sulphide ore containing chalcocite, digenite and covellite using Fe 3+ and bacteria in sulfuric acid aqueous solution has been researched. The detailed leaching process and bacteria leaching mechanism of low grade secondary copper sulphide ore have been demonstrated after dynamic study. The results show that the bioleaching of copper sulphide is mainly by indirect mechanism. According to the research, two paths for increasing copper leaching rate are presented. |
