[0002] At present, the main leaching methods of uranium ore in my country include agitation leaching, heap leaching and in-situ leaching. The choice of leaching method mainly depends on the type of uranium deposit and the characteristics of uranium ore. Agitation leaching is widely used because of its wide application range, simple equipment, convenient operation, short leaching cycle and high uranium leaching rate. The main equipment for agitation leaching is a stirring leaching tank, which can be divided into a mechanical stirring leaching tank and an air stirring leaching tank according to the stirring method. In recent years, with the continuous development of hard rock uranium mines in my country, uranium resources that are easy to leach and have low production costs have been exhausted, and some difficult-to-leach uranium resources have become the main body of development and utilization. The low leaching rate of uranium is generally due to the fact that uranium minerals in uranium ore are difficult to crack, there are many primary uranium minerals, the uranium minerals are fine in particle size, and they are wrapped by gangue minerals. In order to improve the recovery rate of uranium, it is often necessary to increase the grinding fineness, add oxidants, heat, increase the amount of reagents, and extend the leaching time during agitation leaching, resulting in high production costs. At present, when atmospheric pressure stirring leaching equipment is used to leach difficult-to-leach uranium ore, there are generally problems such as low leaching rate, long leaching cycle, and high reagent cost.

[0053] A material separation annular plate 403 is fixed inside the above-mentioned mixing box 401, and the end of the material separation annular plate 403 away from the mixing box 401 is set with rounded corners.

[0056] After the first motor 407 is turned on, the first motor 407 can drive the rotating shaft 404 to rotate, and the rotating shaft 404 drives the stirring rod 406 to start rotating, so as to stir and mix the ore and carbon nanosphere powder transmitted to the interior of the partition ring plate 403. As the ore and carbon nanosphere powder continue to enter, the mixture accumulated inside the partition ring plate 403 gradually exceeds the top of the partition ring plate 403 and falls into the area between the partition ring plate 403 and the mixing box 401. As the mixture continues to fall in, and at this time the second The motor 413 is turned on, and the second motor 413 can drive the second pulley 412 to rotate.

At this time, the connecting rod 507 drives the dispersion rod 504 to start rotating. The dispersion rod 504 rotates toward the outside of the branch rod 502 and is in an expanded state, and then the dispersion rod 504 further extends into the mixed material pile.

[0060] The present invention adopts the above-mentioned leaching device, and the specific use steps are as follows:

[0061] ① Place the ground ore on one conveyor belt 402, and place the carbon nanosphere powder on another conveyor belt 402, and transport them together to the inner area of ​​the partition ring plate 403 inside the mixing box 401;

[0062] ② Turn on the first motor 407 and the second motor 413. The first motor 407 drives the stirring rod 406 to evenly mix the above-mentioned ore and carbon nanosphere powder. The mixed material in the area of ​​the partition ring plate 403 exceeds the boundary of the partition ring plate 403 and falls into the area between the partition ring plate 403 and the mixing box 401. At the same time, the second motor 413 continuously drives the mixing box 401 to rotate, and the mixed material gradually enters the leaching tank 1 along the discharge pipe 409;

[0063] ③ First, water is added to the leaching tank 1. After the mixed material has fallen into the leaching tank 1, the leaching liquid is added to the leaching tank 1. At the same time, the heating resistor plate 302 inside the base 301 is turned on and the conductive coil 6 on the side of the leaching tank 1 is energized to start heating the leaching tank 1;

[0064] ④ While increasing the temperature, turn on the air pump 308 to introduce air into the housing 303;

[0065] ⑤ As the mixed material enters, the cylinder 510 is opened at the same time, and the cylinder 510 drives the adjustment rod 506 to move toward the outside of the leaching tank 1, driving the dispersion rod 504 to open;

[0066] ⑥ After leaching is completed, the heating resistor plate 302 and the conveyor belt 402 are closed, and the solenoid valve 7 on the discharge pipe 409 is opened to discharge the slurry.

[0067] Wherein, in step ①, the added mass ratio of carbon nanosphere powder to ore is: 1:50-60.

[0068] Example:

[0069] Select hard rock uranium ore, first grind the ore to a particle size of 0.2mm, place carbon nanosphere powder and ore with a corresponding mass ratio of 1:50 on a conveyor belt 402, open the two conveyor belts 402 simultaneously, and introduce the mixed material mixed by the mixing box 401 into the leaching tank 1. At the same time, water is continuously added while the mixed material falls in, and the mixed material is continuously covered layer by layer and mixed with water. After the mixed material is added, concentrated sulfuric acid with a concentration of 98% is added to the inside of the leaching tank 1, the temperature of the heating resistor plate 302 is set to 60°C, the air pump 308 is turned on, the conductive coil 6 is turned on, the current intensity of the conductive coil 6 is 15A, and the leaching residence time is 60min.

6. The uranium leaching device for raw uranium ore according to claim 1, characterized in that: The mixing box (401) is provided with a fixed track (415) outside, and the mixing box (401) is rotatably connected inside the fixed track (415). The fixed track (415) is fixed to the side of the leaching tank (1) at the end away from the mixing box (401).

7. The uranium leaching device for raw uranium ore according to claim 1, characterized in that: A guide hole (511) is provided on the side of the leaching tank (1) corresponding to the position where the branch rod (502) extends out, and the guide hole (511) is arranged obliquely, and the guide hole (511) allows the branch rod (502) to slide.

8. A method for leaching uranium from uranium ore, comprising: The device is characterized in that The following steps are involved: ① Placing the ground ore on one conveyor belt (402), placing the carbon nanosphere powder on another conveyor belt (402), and transporting them together to the inner area of ​​the partition ring plate (403) inside the mixing box (401); ② Turn on the first motor (407) and the second motor (413), the first motor (407) drives the stirring rod (406) to evenly mix the above-mentioned ore and the carbon nanosphere powder, and the mixed material in the area of ​​the material separation annular plate (403) exceeds the boundary of the material separation annular plate (403) and falls into the area between the material separation annular plate (403) and the mixing box (401), and at the same time, the second motor (413) continuously drives the mixing box (401) to rotate, and the mixed material gradually enters the leaching tank (1) along the discharge pipe (409); ③ First, water is added to the leaching tank (1). After the mixed material has been added, leaching liquid is added to the leaching tank (1). At the same time, the heating resistor plate (302) inside the base (301) is turned on and the conductive coil (6) on the side of the leaching tank (1) is energized to start heating the leaching tank (1); ④ While increasing the temperature, turn on the air pump (308) to allow air to flow into the housing (303); ⑤ As the mixed material enters, the cylinder (510) is opened simultaneously, and the cylinder (510) drives the adjustment rod (506) to move toward the outside of the leaching tank (1), driving the dispersion rod (504) to open; ⑥ After leaching is completed, the heating resistor plate (302) and the conveyor belt (402) are closed, and the electromagnetic valve (7) on the discharge pipe (409) is opened to discharge the slurry.

9. The method for leaching uranium from uranium ore according to claim 8, characterized in that: In the step ①, the mass ratio of carbon nanosphere powder to ore is 1:50-60.
