Document Type and Number:
WIPO Patent Application WO/2023/173776
Kind Code:
A1
Abstract:
Disclosed are a recovery method and recovery system for a ternary precursor mother liquor. The recovery method for a ternary precursor mother liquor provided in the present invention comprises the following steps: S1, reacting sulfide ions with a ternary precursor mother liquor, and then performing solid-liquid separation; S2, reacting an oxidant with liquid phase components obtained in step S1, and then performing solid-liquid separation; S3, treating, with quicklime, liquid phase components obtained in step S2, and collecting obtained gas; S4, performing, with sulfur dioxide, aeration treatment on a residual mixture in step S3, and then performing solid liquid separation; and S5, performing crystallization treatment on liquid phase components obtained in step S4. According to the recovery method for a ternary precursor mother liquor of the present invention, solutes in the ternary precursor mother liquor can be converted into products having high economic benefits; meanwhile, the treated ternary precursor mother liquor has few impurities, and high environmental protection benefits are achieved. The present invention further provides a recovery system for implementing the recovery method.
