| titleOfInvention | A kind of uranium purification process of ammonium diuranate |
| abstract | The invention belongs to the dissolution purification process technology fields of ammonium diuranate in uranium purifying conversion process, specifically include the dissolution of ammonium diuranate, the technologies such as uranyl nitrate solution abstraction purification processing.Include the following steps：(1) it dissolves, qualified uranyl nitrate solution is prepared for abstraction purification；(2) it extracts, makes to extract stoste and extractant mixes mass transfer in pulse extraction column, the uranium carrier band in material is entered in extractant, uranium-bearing organic phase is obtained；(3) it washs, so that uranium-bearing organic phase and detergent is sufficiently mixed mass transfer in pulse column scrubber, the impurity element in uranium-bearing organic phase is relaundered into water phase, further increase the purity of uranium, the uranium-bearing organic phase after being purified；(4) it is stripped, purified uranium-bearing organic phase and detergent is made to be sufficiently mixed mass transfer in pulse column scrubber, uranium is stripped again and is entered in water phase, uranyl nitrate solution after purification is obtained；Uranyl nitrate solution after purification prepares uranium oxide by way of denitration is concentrated again. |
