The role of micro-organisms in the formation of acid mine drainage .The drainages from the Margerita group of mines are found to be acidic with high sulphate ranging up to 1500 ppm and iron content rising up to 40 ppm. The total sulphur in coals is up to 7% out of which 50–80% is non-reactive organically found sulphur. The acidity mainly arises from the oxidation of pyrites of coal.the role of microorganisms in coal mining,isolation, identification and characterization of bacteria in .compete for available inorganic substrates. It is therefore impossible as yet to define the precise role and importance of each organism in these dynamic populations, as the intimate link between microbial physiology and sulfide bio hydrometallurgy is incompletely understood [17] [11]. Coal mine spoil overburden represents.
