6 Potential Environmental Effects of Uranium Mining

Acid mine drainage. Acid mine drainage (AMD) has the potential to be one of the most serious environmental problems caused by uranium mining in the Commonwealth of Virginia if it is not appropriately managed and mitigated. AMD is formed through oxidation of metal sulfides (e.g., FeS 2) present in the ore or waste materials by a group of acidophilic microorganisms (Campos et al., 2011).
