Acid mine drainage USGS
Acid mine drainage (AMD) consists of metalladen solutions produced by the oxidative dissolution of iron sulfide minerals exposed to air, moisture, and acidophilic microbes during the mining of coal and metal deposits. The pH of AMD is usually in the range of 2–6, but mineimpacted waters at circumneutral pH (5–8) are also common. Mine drainage usually contains elevated concentrations of ...
