What is Acid Drainage? - International Network for Acid Prevention
If the rock contains sulphides, a natural oxidation process can acidify the water. This is known as acid drainage (also acid rock drainage (ARD) or acid mine drainage (AMD)). As the water becomes more acidic, its capacity to leach out other elements from the rock, such as metals, increases. The resulting drainage ...
