Vol. 24 No. 3 - July 2018. Role of microorganisms in reclamation of coal-mine spoils. By: R S Upadhyay 1 and Richa Raghuwanshi 2. Introduction. The fossil fuel coal is largely valued for its energy content. Since the 1880s it has been primarily and widely used for electric/power generation.

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.

Oct 01, 2020  The composition of the microbiome of acid drainage water of a quarry used for the mining of brown coal was studied. The water had a pH of 5.15 and contained 1.4 g/L of sulfate. Unlike acid mine drainage associated with mining of sulfide ores, the content of iron and heavy metals was low. Molecular analysis of the microbial community was performed by high-throughput sequencing of the 18S and ...

Acidophiles in acid mine drainage - Wikipedia

The outflow of acidic liquids and other pollutants from mines is often catalysed by acid-loving microorganisms; these are the acidophiles in acid mine drainage.. Acidophiles are not just present in exotic environments such as Yellowstone National Park or deep-sea hydrothermal vents. Genera such as Acidithiobacillus and Leptospirillum bacteria, and Thermoplasmatales archaea, are present in ...

Acid mine drainage - microbewiki

Aug 26, 2010  Acid mine drainage (AMD) occurs when metal sulfides, most commonly pyrite, are exposed to and react with air and water. When water flows over or through sulfur-bearing mine tailings, a chemical reaction occurs between the water and rocks resulting in metal-rich water.
