Bacterial Leaching of Minerals | SpringerLink
The bioleaching process has been restricted to copper and uranium extraction using heap, dump and in situ leaching technologies from mining wastes and low grade mineral resources. In these, the contribution of microorganisms was not appreciated. Thiobacillus ferrooxidans, the most studied microorganism, has been found responsible for the ...
