Kinetic Models of AMD in the Area of Post-mining Lakes in the Eastern Part of Muskau Arch ☆

Abstract As a result of lignite exploitation within the area of Muskau Arch, the group of artificial lakes was formed. Their chemistry is a consequence of acid mine drainage (AMD), which starts from the intensive weathering of pyrite (FeS 2 ), that is present in Miocene lignite-bearing rock, forming the embankments of the lakes. Finally this process leads to heavy acidification of water and elevated concentrations of sulfates and metals. This paper discusses the kinetic models developed to characterize the rate and general course of AMD in the analyzed region.
