Electrokinetic device and method for in-situ leaching of uranium

An electrokinetic device for in-situ leaching of uranium, comprising:

• 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;
• 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 pooling of uranium-carrying ions towards the pumping well;
• the injection well comprises a cathode chamber, an injection chamber, and an anion exchange membrane;
• the pumping well comprises an anode chamber, a pumping chamber, and a cation exchange membrane;
• the anion exchange membrane is provided between the cathode chamber and the injection chamber, and the cation exchange membrane is provided between the anode chamber and the pumping chamber;
• the negative electrode is arranged in the cathode chamber, and the positive electrode is arranged in the anode chamber;
• the uranium ore is provided between the injection chamber and the pumping chamber;
• and
• the leaching solution is injected from the injection chamber, flows through the uranium ore, and then is pumped from the pumping chamber;
• wherein the cathode chamber and the anode chamber each are filled with electrode protection solution.
