Fe~(3+) behavior in the low copper bioleaching

YANG Hong-bin~1, JING Xiu-yan~2(1.College of Envrionmental Science and Engineering, Chang'an University,Xi'an 710054, China;2.Dept. of Geology and Environmental Engineering, Xi'an University of Science and Technology, Xi'an 710054, China)  
The leaching rate of aimed ore often was affected by Fe~(3+) deposition in the course of leaching. The paper analyses each factor about Fe~(3+) in order to ensure oxidation reaction effectively and reduce the Fe~(3+) deposition. The analysis indicates that matching the relation among the pH value, iron concentration, oxidizing activity and radox potential was the key to keep Fe~(3+) deposition least, on the base of bacteria adapting lower acid.
