| Abstract: |
| The tests for shaking- and column-leaching of low-grade ore from Tongkuangyu Copper Mine are carried out in laboratory The testing results show that the leaching rate of copper can be increased by over 10% with bacterial leaching In order to solve the problems of low temperature and inadequate oxygen in underground leaching,the process of bacterial oxidation ferrous followed by ferric oxidation-leaching sulfide ore is used in production In addition,project investment,techno-economical indexes and environmental influence are discussed The bacterial leaching can improve the utilization of mineral resources,with less investment and short capital return term |
