ACID MINE DRAINAGE

ACID MINE DRAINAGE J Donald Rimstidt1 and David J Vaughan2 When metal sulfi de minerals are exposed to air and water, they break down and give rise to acidic, sulfate-rich waters contaminated with dissolved metals, particularly iron Most commonly, this exposure is due to mining, and the waters are called acid mine drainage (AMD).
