Beneficiation method for recovering uranium from rare earth ore
The invention discloses a beneficiation method for recovering uranium from rare earth ore. The beneficiation method comprises the steps that uranium-containing rare earth ore is finely crushed and then classified, and coarse-fraction ore and fine-fraction ore are pre-enriched through a dense medium...

| description | The invention discloses a beneficiation method for recovering uranium from rare earth ore. The beneficiation method comprises the steps that uranium-containing rare earth ore is finely crushed and then classified, and coarse-fraction ore and fine-fraction ore are pre-enriched through a dense medium cyclone and a high-intensity magnetic separator correspondingly; after the mixed rough concentrate is reground, rare earth minerals are firstly subjected to flotation, uranium minerals are then subjected to flotation, and after flotation uranium concentrate is reground, the uranium grade is further improved through weak magnetic iron removal; and after scavenging tailings in the flotation process are reground, uranium ore is further separated and enriched through reselection, the uranium concentrate subjected to reselection is subjected to strong magnetic separation, the uranium grade is improved, the yield of the finally obtained uranium concentrate is 5.50%, the uranium grade is 0.27%, and the recovery rate is 71 |
