Acid Mine, Drainage (AMD) is a ,wastewater, formed through a series of chemical reactions and biological activities during and after open-pit system coal exploitation. Coal containing sulfide in the presence of oxygen and air is oxidized to form sulfuric ,acid,, thus having a pH<4. This condition facilitates the solubility of Fe and Mn. As a result, AMDhas a great potential as environmental polluters.
