Description:   The mineralogical transformation associated with acid generation in a waste rock pile was described by studying the South waste rock dump at the Mine Doyon site.  Waste rock samples were analyzed by X-ray diffraction and by scanning electron microscopy.  Pyrite, the source of acidity on the dump, was not depleted, while neutralizing minerals like carbonates were almost completely depleted.
