Application of Microbial Ore Leaching -

1. Extraction of metals from ores, e.g., copper, as their sulphates.
2. Partial leaching of mineral concentrates to remove impurities.
3. Conversion of a mineral into a form suitable for processing by other means.
4. To generate ferric sulphate for leaching of other metals, e.g., uranium, which may be toxic to the microbes.
