  • Mining MillingCameco U101

    Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper gold or nickel.

    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.
