Fate of manganese and radionuclides applied in uranium
In a field experiment we investigated the retention of 238 U, 226 Ra, 210 Pb, 54 Mn and 22 Na under conditions similar to those used by the mine A plot measuring 135 m×45 m, was established next to the Ranger Uranium Mine in a previously unirrigated area of the most dominant soil type of the land application areaMany authors used manganese dioxide and oxy Uranium Mining Effluent by a RadiumSelecti ve Ion Exchange Complexer,” Metallurgical Society of CIM Bulletin, (PDF) Removal of Radium from Uranium Effluent by Excess mine waste water is being disposed by irrigation of bushland near Ranger Uranium Mine, Northern Territory, Australia We report the sorption properties of highly weathered and sandy soils (Utric Acruustox, Grossameric Kandiustalf, and Typic Fragiumbrept), near the mine for Mn, U, and 226 Ra as determined by batch sorption experiments Sorption of Manganese, Uranium, and Radium by Highly
