| titleOfInvention | Method for continuously synthesizing precursor by washing filter material with hydroxide and secondary crystallization |
| abstract | The invention discloses a method for continuously synthesizing a precursor by washing a filter material with hydroxide and performing secondary crystallization, the method recycles the mother liquor and the hydroxide fine particles in washing through a filter press or micropores, pulpifies the recycled filter materials, and the solid content of the pulped filter material is ensured to be 1-5 times of the solid content of the slurry in the reaction kettle, the pH value of the pulped filter material is less than or equal to the pH value of the slurry in the reaction kettle, the content of the complexing agent is within 60-100% of the concentration of the complexing agent of the slurry in the reaction kettle, the pulped filter material is quantitatively and continuously added into the synthesis reaction kettle to be used as a crystal seed for secondary crystallization synthesis growth, and the controllability of the filter material added into the reaction kettle is realized by adjusting the flow rate and the solid content of the filter material, and according to the grain size growth trend, the specific addition amount is adjusted through flow rate to realize continuous synthesis of the precursor. The invention can effectively utilize fine particles generated during the synthesis of the precursor, greatly improve the productivity and the yield of valuable metals, and effectively reduce the treatment cost. |
