| titleOfInvention | A kind of extraction method of uranium in chlorocarbonate system |
| abstract | The invention relates to the field of wastewater treatment technology, in particular to a method for extracting uranium in a chlorine-containing carbonate system. The method is as follows: adding an adjusting agent to the chlorine-containing uranium carbonate solution for adjustment, and the pH value of the adjusted solution is 4-8; inputting the adjusted solution into an ion exchange device, and adsorbing the solution by an ion exchange method. When the uranium concentration in the tail liquid reaches the breakthrough concentration or the resin tower used for adsorption is saturated, the saturated resin tower is cut into the elution transformation operation, and the liquid in the tower is emptied; The leaching lean liquid is used for leaching the saturated resin tower; the resin tower after rinsing is emptied of the liquid, and a transformation agent is added to the lower liquid to transform the resin, and the transformed resin tower is reused for adsorption; Wash the uranium in the qualified solution. The invention solves the problems of difficulty in uranium extraction and leaching in the chlorocarbonate system, and improves the adsorption capacity. |
