| Abstract: | Summary Direct bioleaching (no iron(II) present) by Thiobacillus ferrooxidans mainly occurs on the surface of the very insoluble sulphides but is more important in solution when the sulphides are more soluble. In this case, Thiobacillus thiooxidans, normally not able to leach directly insoluble sulphides, has an effective leaching action. |
