Role of microorganisms in reclamation of coal-mine spoils
Microbial communities play a crucial role in improving the soil fertility and productivity by breaking down organic matter into inorganic forms of mineralized nutrients accessible for plant uptake. During opencast mining, the mine spoils or overburdens created are often devoid of essential nutrients and have relatively lower water holding capacity.

Review Role of Microorganisms in Mining: Generation of
Microorganisms, mainly bacteria as mentioned above, are indigenous to the ARD environment. These microorganisms play a role in the direct and indirect oxidation of sulphur minerals (e.g., pyrite, pyrrhotite). Normally, sulphur oxidizing bacteria are incorporated for extracting metals from ores in metallurgical processes.

The Role of Microorganisms in Acid Mine Drainage:
Various coals were examined by these workers for the possible role of microorganisms in the change of the sulfur content. By comparing sterilized with nonsterilized portions they concluded that at least part of the sulfate produced in acid mine water can

Mining With Microbes American Chemical Society
Oct 15, 2012Instead of separating the metal from the pyrite with high temperatures or pressures, biomining uses microbes from the Acidithiobacillus and Leptospirillum genera to do the job. These microbes have protein systems that can oxidize Fe 2+ to Fe 3+, which they use to generate chemical energy for their metabolic processes, Dold says.

Nov 06, 2020Sulphur-oxidising bacteria also have a role to play in the coal mining industry. Increased environmental awareness in many countries means that it is no longer acceptable to burn off the sulphur content of coal as sulphur dioxide, so an alternative must be found.
