Subjects: Acid mine drainage.; Waste rock dumps.
Description:   The processes which control acid generation in waste rock piles, namely precipitation, dissolution, chemical diffusion, and surface reactions, were described. Geochemical computer models were evaluated according to their ability to describe the geochemical processes and their applicability to the prediction of water quality from waste rock piles. The models that were evaluated included, among others, geochemical mass transfer models, supporting geochemical models, and empirical and engineering models.
Notes: Summary in English and French.
