Acid mine drainage is a serious environmental issue in the coalmining areas of Northeast India. Coals of Northeast India, namely Assam, Meghalaya, Arunachal Pradesh, and Nagaland, contain high sulfur (2–7 %), high volatile matter (30–50 %), and low ash (Mukherjee, 2003; Singh et al., 2012, 2013).

The high-sulfur/iron environment in the mining area recruited the accumulation of a large number of Sphingomonas, Thiobacillus, Lysobacter, Bacteroides, and Sulfurifustis in the soil (Fig. 2 E). Of these, Thiobacillus (Betaproteobacteria) can oxidize and utilize S. Hence, it plays a vital role in the S cycle.

Due to the high input of Fe(II), ferric iron precipitates in the pelagial with high sedimentation rates (570 g m −2 a 1) yielding a brownish orange, fluffy, upper sediment zone rich in reactive iron (Fig-ure 2) (Peine et al., 2000). With increasing sediment depth, the amount of react-ive iron ...

Sulfur is mined from both surface and underground deposits, and is recovered as a byproduct from a number of industrial processes. In sulfur mining, three techniques are applied: conventional underground methods, conventional open pit methods, and the Frasch mining method. About 90% of all sulfur mined is obtained through Frasch mining.5

They are removed by the Frasch process. It ranks about number 16 among the elements in terms of their abundance in the earth. The largest producers of sulfur in the world are the United States, Canada, China, Russia, Mexico, and Japan. In 1996, the United States produced about 11,800,000 metric tons of sulfur.

The flow of AMD is fully dependent on the seasonal change in the mining site. AMD generated from high-sulfur coal in Ledo opencast mining is highly acidic in monsoon season, having pH as low as 3.3. This high acidic character of AMD creates a major threat to water bodies in habitat areas due to the dissolution of PHEs.
