Leaching of Zinc Sulfide by Thiobacillus ferrooxidans
The role of Thiobacillus ferrooxidans in bacterial leaching of mineral sulfides is controversial. Much of the controversy is due to the fact that the solution conditions, especially the concentrations of ferric and ferrous ions, change during experiments. The role of the bacteria would be more easily discernible if the concentrations of ferric and ferrous ions were maintained at set values

Bioleaching metal solubilization by microorganisms FEMS
The procedure is similar to that of dump leaching. In some heap leaching operations, pipes are placed in strategic positions within the heaps during its construction to provide the deeper portions of the heap with sufficient amounts of oxygen. 5.2.3 Underground leaching. Underground leaching is usually done in abandoned mines.
