Abstract

Closure of uranium mines often result in formation of acid mine drainage (AMD). Usually AMD contains high concentrations of uranium and other heavy metals, which may influence the ambient environment of the mine. To prevent this, restoration measures are required. A feasible way to ensure pollutant immobilization is the utilization of the mine sites natural-attenuation potential, which may be furthermore enhanced by injection of reactive materials. Stimulation of autochthonous sulphate-reducing bacteria would subsequent lead to a reductive reaction zone within the mine.
