Acid mine drainage microbewiki

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 sulfurbearing mine tailings, a chemical reaction occurs between the water and rocks resulting in metalrich water. AMD typically has a bright orange, yellow, or bownishred color to it.
