  • WMANEnvironmental Impacts of Mining

    Mining unearths large amounts of ore that contains precious metals, such as gold and silver, as well as iron and other sulfides. When sulfides in the ore are exposed to water and air, sulfuric acid is created, which can seep from mines and waste rock piles into streams, rivers, and groundwater. This seepage is called acid mine drainage.
