the role of microorganisms in coal mining

Oct 09 2014 Microorganisms 19 bacteria strains were selected which were isolated from soil mixed with coal residues coal sediment resulting from coal washing and the rhizosphere of Cenchrus ciliaris and Typha domingensis two plants from the gramineae family which grow on soil and sediments with high amounts of coal particles in areas under the influence of the open pit coal extraction activities

Role of microorganisms in reclamation of coal-mine spoils

It has been demonstrated by various studies that vegetation has a significant influence on the abundance of microorganisms in surrounding bulk soil and rhizosphere. Plants adapted to grow on polluted sites can be used for restoration of coal-mine spoils to improve soil structure and organic content.

Microbiological Mining

For many years the only microorganism thought to be important in the leaching of metals from ores was the rod-shaped bacterium Thiobacillus ferrooxidans. This microorganism was discovered in the acidic water draining coal mines; it was not until 1957 that a correlation was recognized between the presence of the bacterium and the dissolution of metals in copper-leaching operations. Since then a great deal
