    Uranium processing preparation of the ore for use in various products.. Uranium (U) although very dense (19.1 grams per cubic centimetre) is a relatively weak nonrefractory metal. Indeed the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements so that it is not valued for structural applications.

    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.

    This work reports a three-step process for synthesizing UN at temperatures below 1200 °C. UO 2 is first converted to tetravalent ammonium uranium fluorides at 20 °C by ball-milling with solid ammonium bifluoride. Then these ammonium uranium fluoride species are reacted with an ammonia atmosphere at 800 °C.
