Uranium acid mine drainage Wikipedia

Uranium acid mine drainage (UAMD) refers to acidic water released from a uranium mining site using processes like underground mining and insitu leaching. Underground, the ores are not as reactive due to isolation from atmospheric oxygen and water. When uranium ores are mined, the ores are crushed into a powdery substance, thus increasing surface area to easily extract uranium.
