| titleOfInvention | A kind of method for strengthening zincblende Microorganism Leaching |
| abstract | The invention discloses a kind of method for strengthening zincblende Microorganism Leaching, comprise the following steps：（1）Zincblende sample ore is smashed into particle, while the pyrite sample ore and/or chalcopyrite sample ore that will add also smash into particle；（2）By culture medium, zincblende, and the pyrite and/or chalcopyrite that will be added carry out autoclave sterilization；（3）Zincblende after sterilizing is added in the shaking flask equipped with culture medium, then is separately added into pyrite or chalcopyrite, and is inoculated with leaching microbacteria；（4）By step（3）Shaking flask place constant-temperature table culture；（5）Determine the leaching efficiency of zinc in leaching process.The present invention in zincblende Microorganism Leaching system by adding pyrite, so that the pH in solution is relatively low, iron concentration and oxidation-reduction potential are higher, under the synergy of microorganism and physical chemical factor, strengthen the oxidation Decomposition of zincblende, significantly increase the leaching rate of zinc.Efficient leaching of the present invention to zincblende provides technological guidance. |
