| Abstract: |
| Effects of slurry concentration, leaching temperature and pressure, metallic ion concentration, colloid material, and ore size on slurry filtration performance of uranium acid pressure leaching were studied. Several methods to improve filtration were discussed. The results show that under the condition of fitting uranium leaching rate, the key affecting factors on filtration speed of slurry include crystalline form of trivalent iron and its concentration in solution. |
