What can be done to prevent or clean up acid mine drainage ...

Water flowing through active or abandoned mine sites can become polluted by the material being mined[1]. By far the most common mine drainage problem is that of acid mine drainage (AMD). Sulfuric acid is produced when water interacts with sulfur-bearing materials in the presence of oxygen and common bacteria[1]. The acidic water formed by this process can dissolve many metals in bioavailable ...

Acid Mine Drainage - Yukon Conservation Society

Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur (metal sulfide mines). A significant number of coal mines also suffer from acid mine drainage. The metals dissolved by the acid drainage poison downstream waters, in many cases to the point where nothing other than
