Environmental impact of mining - Wikipedia
Environmental impact of mining - Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...

A series of complex reactions between pyrite, oxygen, and water result in acid mine drainage. Acid mine drainage is wastewater that is extremely acidic and contains high concentrations of heavy metals. Acid mine drainage is one of the major sources of stream pollution in the Appalachian mountain region. Acid mine drainage has severely damaged more than half the streams in Pennsylvania and West Virginia.
