Geochemistry of Acid Mine Drainage - Viadero - -

Acid mine drainage (AMD) results when metal pyrites come in contact with water and/or air, to form dilute sulfuric acid. For instance, iron pyrite (FeS 2) is the major iron‐sulfur impurity found in mined earth, particularly in the eastern United States where coal mining is prevalent.Typically, AMD waters contain elevated concentrations of SO 4, Fe, Mn, Al, and other metal ions.

Hydrogeology and geochemistry of acid mine

Acid drainage from the Penn Mine in Calaveras County, California, has caused contamination of ground water between Mine Run Dam and Camanche Reservoir. The Penn Mine was first developed in the 1860's primarily for copper and later produced lesser amounts of zinc, lead, silver, and gold from steeply dipping massive sulfide lenses in metamorphic rocks.

Treatment of acid mine drainage by four vertical flow ...

Acid mine drainage (AMD) is a serious problem in many watersheds where coal is mined. Passive treatments, such as wetlands and anoxic limestone drains (ALDs), have been developed, but these technologies show varying treatment efficiencies. A new passive treatment technique is a vertical flow wetland or successive alkalinity producing system (SAPS).
