  • Uranium processing Canadian Nuclear Association
    Uranium MillingRefining & ConversionEnrichmentFuel ManufacturingAfter mining, uranium ore is transported to a nearby mill for processing. The first step is to crush the ore and mix it with water so that it can move through a series of mill circuits. After crushing, the ore is treated with acid in large tanks, to separate the uranium from other minerals in the rock. The uranium is now part of a liquid solution, which is then separated from the other minerals, which remain solid. The uranium-rich solution is theSee more on cna.ca

    For light water reactors that require higher concentrations of U 235, the next step is conversion to uranium hexafluoride (UF 6), a chemical form suitable for enrichment.During this conversion process, the UO 3 is combined with fluorine compounds to create UF 6.UF 6 is the only uranium compound that can exist as a gas, a liquid or a solid, depending on pressure and temperature.
