There are four chemical reactions that represent the chemistry of pyrite weathering to form acid mine drainage. An overall summary reaction is as follows: 2 FeS2+7 O2+2 H2O → 2 FeSO4-+2 H2SO4 Pyrite + Oxygen + Water → Ferrous Sulfate + Sulfuric Acid. The acid mine drainage waste is characterized by red water. The simplest treatment is neutralization and clarification.

The biogeochemistry ,of acid mine, drainage (AMD) derived from waste rock associated sulfide mineral oxidation is relatively well-characterized and linked to Acidithiobacillus spp.. However, little is understood about the microbial communities and sulfur cycling before AMD develops, a key component of its prevention. This study aimed to examine circum-neutral mining impacted water (MIW ...
