11/5/2020, · The acid mine water or industrial acid mine drainage (I-AMD), also known as acid rock drainage is one of the most, serious, and, hazardous environmental challenges, caused by mining. Two physicochemical characteristics which make I-AMD so hazardous are: an extremely acidic pH (<4) and a high concentration of heavy metals ( HM s) [ 3 , 4 ].
