    Uranium processing - Canadian Nuclear Association

    After 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.

    JETMINE extraction and processing method is similar to the ISL process but without the use of chemicals. THE URANIUM INDUSTRY TODAY. Due to the worldwide oversupply of uranium, and a dearth of new U.S. nuclear plants, the U.S. uranium mining industry was depressed from the early 1980s until about 2003 when only a few mines remained in operation.

    Radioactive Waste From Uranium Mining and Milling | US EPA

    After uranium is extracted from rock, the processes leave behind radioactive waste. Uranium eventually decays to radium, and then radon. Open pit uranium milling and in situ mining sites do not pose a radon risk to the public or miners.

    Uranium Processing | Teach Nuclear

    Here, the uranium is separated from impurities through a series of chemical processes, including digestion, solvent extraction, and denitration. These refinement methods produce high-purity uranium trioxide (UO 3). The uranium conversion process for CANDU heavy water reactors involves converting UO 3 to uranium dioxide (UO 2). This takes place ...

    ISR Mining - Uranium One

    ISR mining technology was developed independently in both the Soviet Union and the United States in the mid-1960's. The method was developed to extract uranium from typical roll‐front type deposits (a sub‐type of sandstone uranium deposits) located in water‐saturated permeable sediments that were not suitable for economical conventional mining techniques.

    Nuclear reprocessing - Wikipedia

    Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors.
