		Some Chemistry of Uranium ^Votes:0 Some Chemistry of Uranium Some Chemistry of Uranium Year 12 October 2007 Occurrence In sea water, at about 0.003 ppm. In rocks of the Earth's crust generally, at up to 4 ppm, and incorporated into many minerals. In ore, as uraninite (UO 2 ) or pitchblende (U 3 O 8 ) or as secondary minerals (complex oxides, silicates, phosphates, vanadates). Australian ores are up to O.5% U 3 O 8 , in Canada they range up to 25% U 3 O 8 . U 3 O 8 is a stable complex oxide: U 2 O 5 .UO 3 . Uranium is fairly soluble and uranium oxide precipitates from uranium-bearing groundwaters as they enter a reducing environment. It can be mobilised (redissolved) in situ by oxygenated leach solution. Extraction from ore, at the mine The ore is crushed and ground to liberate the mineral particles. It is then leached with Read More Go to Site
