    Pyrite

    Pyrite exposed to the environment during mining and excavation reacts with oxygen and water to form sulfuric acid, resulting in acid mine drainage. This results from the action of Thiobacillus bacteria, which generate their energy by using oxygen to oxidize ferrous iron (Fe 2+ ) to ferric iron (Fe 3+ ).
