  • Patent number: 12168813
    Abstract: Provided are an electrokinetic device and method for in-situ leaching of uranium. The electrokinetic device for in-situ leaching of uranium includes an injection well, a pumping well, a positive electrode, a negative electrode, leaching solution, and a direct current power supply. Uranium ore is provided between the injection well and the pumping well, the negative electrode is arranged in the injection well, and the positive electrode is arranged in the pumping well. The leaching solution is injected from the injection well, flows through the uranium ore, and then is pumped from the pumping well for uranium extraction. The direct current power supply is respectively connected to the positive electrode and the negative electrode, and is configured to apply direct current between the positive electrode and the negative electrode to promote the pooling of uranium-carrying ions towards the pumping well.
