• InSitu Uranium Mining Process UrEnergy

    The pump in the production well collects the uranium laden water and sends it to the processing plant where the uranium is removed by ion exchange. The water is then refortified with oxygen and baking soda and sent back to the ore zone to recover more uranium. The native groundwater continues in this cycle until uranium extraction is complete.

    The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine. The cutter is a cutting tool with sharp teeth that is also secured in the milling machine and rotates at high speeds.

    was used, the uranium is already dissolved in solution. The chemicalore solution undergoes further treatments to separate the uranium as a precipitate. Uranium is collected and dried as uranium oxide (U 3 O 8) concentrate. The concentrate is a powder called yellowcake. This process of removing uranium from the ore is called uranium milling.

    The vast majority of nuclear power reactors use the isotope uranium235 as fuel; however, it only makes up % of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium235 concentration from % to between 3% and 5%, which is the level used in most reactors.
