Acid mine drainage Wikipedia
Although a host of chemical processes contribute to acid mine drainage, pyrite oxidation is by far the greatest contributor. A general equation for this process is: . [7] The oxidation of the sulfide to sulfate solubilizes the ferrous iron ( iron (II) ), which is subsequently oxidized to ferric iron ( iron (III) ): .

Acid mine drainage microbewiki Kenyon College
Exposing pyrite to oxygen and water leads to an oxidation reaction, where hydrogen and sulfate ions and soluble metal cations are created: 2FeS 2 (s) + 7O 2 (g) + 2H 2 O (l) → 2Fe 2+ (aq) + 4SO 42 (aq) + 4H + (aq) Pyrite oxidation occurs naturally at a slow rate in undisturbed rock. However, the acidity created is buffered by water.
