AMD always means that ARG has occurred. But ARG does not necessarily imply AMD.

  • Acid rock generation (ARG) implies
    • exposure of sulfide minerals to air and moisture by any cause, natural or man-made. A natural cause may for example be a volcanic eruption. Anthropogenic causes may be for example mining activities or road construction.
    • formation of acidity and metal ions by bioleaching
  • Acid rock drainage (ARD) implies
    • exposure of sulfide minerals to air and moisture by any cause, natural or man-made.
    • formation of acidity and metal ions by bioleaching
    • Leachate escapes from the source of formation
  • Acid mine drainage implies
    • Mining activities expose sulfide minerals to air and moisture
    • formation of acidity and metal ions by bioleaching
    • The leachate - acidity and heavy metals - drains to the surroundings. For example leachate may escape to groundwater.
