  • Acid Mine Drainage   Ground Truth Trekking

    Acid Mine Drainage Ground Truth Trekking

    Summary. Acid mine drainage (AMD) refers to the outflow of acidic water from a mining site. In most cases, this acid comes primarily from oxidation of iron sulfide (FeS2, also known as pyrite or quot;fool's goldquot;), which is often found in conjunction with valuable metals. Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore
