How can acid mine drainage be treated?

Treatment of AMD: Acid mine drainage sometimes forms when certain minerals in the soil and rocks around mines are exposed to weathering processes during mining.These exposed minerals release their contents into creeks causing them to become acidic. This kind of pollution damages aquatic life and makes the water useless or harmful for others who depend on it for recreation or drinking water.

Acid Mine Drainage (AMD) / Acid Rock Drainage (ARD)

Acid Rock Drainage as a concern and part of all metals and mining operations. ARD is often mislabelled AMD or Acid Mine Drainage too.
