| titleOfInvention | A kind of holmium oxide separation process |
| abstract | The invention provides a holmium oxide separation process, which comprises the following steps: saponifying the mixture of P507 and sulfonated kerosene to obtain organic load A, which is added to 1# extraction tank; Separation and extraction are carried out in the 2# extraction tank connected with the 1# extraction tank, and the organic load B and the organic load C are respectively drawn out; the organic load B is washed in the 3# extraction tank to obtain middle rare earth and holmium containing a small amount of yttrium after enrichment. Feed liquid; introduce it into 4# extraction tank for separation and extraction, and draw out organic load D; add it to 5# extraction tank for separation and extraction to obtain a mixture of yttrium chloride and holmium chloride; add light to 6# extraction tank Rare earth is organically loaded with E, and a mixture of yttrium chloride and holmium chloride is introduced for separation and extraction to obtain enrichments of pure holmium chloride and yttrium chloride respectively; Get holmium oxide. The holmium oxide separation process of the present application has low energy consumption, high efficiency and low cost. |
