    The Health and Environmental Impact of Uranium Mining

    Uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. These tailings pose serious environmental and health risks in the form of Randon emission, windblown dust dispersal and leaching of contaminants including heavy metals and arsenic into the water.

    Nov 01, 2021 Introduction. Acid mine drainage (AMD) is a global environmental problem primarily caused by microbially mediated oxidative dissolution of sulfide minerals (mainly pyrite, FeS 2) exposed to air and water (Akcil and Koldas, 2006).High acidity and high-concentration heavy metals and sulfate make AMD environments extremely stressful or hostile for most

    Jul 10, 2014 Chemical analysis of soil and sediment samples at the mine site is an important step in detecting the presence of environmental contaminates that may remain as a result of mining activities. Both Energy dispersive x-ray fluorescence (EDXRF) and wavelength dispersive x-ray fluorescence (WDXRF) are good solutions for this analysis
