| Abstract: | Physical mutation on Thiobacillus ferrooxidans and a moderately thermophlic strain from hot spring water by utraviolet-ray and the bioleaching of chalcopyrite ores are studied.The results show that the bacterium after mutation,compared to the original,an increase of 40.6% and 35.9% in activity,and an improvement of 36.6% and 23.5% in the leaching rate,and the study of mixed bacteria leaching with the two bacteria has been made. |

| Keywords: | Thiobacillus ferrooxidans Moderated thermophlic strain Utraviolet-ray Chalcopyrite Mixture of bacteria. |
