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 ...

Nuclear Fuel Cycle. Source: Nuclear Regulatory Commission from US. License: CC BY 2.0 Uranium milling is a series of mechanical and chemical processes, which processes extracted uranium ore and produces dry powder-form material consisting of natural uranium, which is called "yellowcake" (chemically U 3 O 8) because of its yellowish color.
Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for ...
