Environmental chemistry of uranium



The purpose of uranium mining is to produce fuel for civilian nuclear power plants and for military programs. Extraction of uranium ores, milling and chemical processing to prepare a uranium concentrate, known as yellow cake (U 3O 8), are accompanied by the production of large amounts of solid and liquid residues. They contain

NRC: Conventional Uranium Mills



May 15, 2017· At the heart of the NRC's regulatory definition of uranium milling, is the concept of the mill tailings produced by the extraction and concentration of uranium. Mill tailings are the fine-grained, sandy waste byproduct material that remains after the milling process has extracted and concentrated the uranium from the ore.

Uranium Mining Overview - World Nuclear Association



Uranium Mining In the last fifty years uranium has become one of the world's most important energy minerals. It is used almost entirely for making electricity, though a small proportion is used for the important task of producing medical isotopes.

Acid Leaching of Uranium



Acid leaching has been used in the uranium milling industry since the mid-forties and has accounted for a majority of the production since that time. It is preferred over carbonate leaching because of its greater efficiency in recovering uranium. Consequently much research has been done on the factors which influence the kinetics of the oxidation of uranium, as well as those which influence ...

Uranium - Wikipedia



Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.
