Biogeochemical Cycles of Acid Mine Drainage The biogeochemical cycles of acid mine drainage from pyrite mines mainly include the following processes: (1) oxidation of pyrite; (2) reduction of sulfate; (3) oxidation of sulfide; (4) disproportionation of sulfur. Reduction of sulfate The reduction of sulfate is one of the important processes of the biogeochemical cycles of acid mine drainage from pyrite mines, which can alleviate the acidity of acid mine drainage, and also produce some beneficial or harmful substances.	cache/fbem-21450.pdf	txt/fbem-21450.txt
