| titleOfInvention | A kind of preparation method of cobalt tetroxide |
| abstract | The invention discloses a preparation method of cobalt tetroxide, which specifically includes the following steps: step 1, preparing cobalt hydroxide slurry; step 2, filtering the cobalt hydroxide slurry in step 1 to prepare cobalt hydroxide and Spherical cobalt mother liquor; Step 3, adding the spherical cobalt mother liquor of the step 2, sodium hypochlorite and sodium hydroxide co-currently into the reaction kettle for reaction, and controlling the redox potential, pH value and reaction temperature of the reaction kettle to obtain cobalt oxyhydroxide Step 4: filter, wash, dry and calcine the cobalt oxyhydroxide in step 3 to obtain tricobalt tetroxide; the present invention will recover the cobalt oxyhydroxide intermediate product ball cobalt mother liquor in the process of preparing cobalt hydroxide without returning to leaching process, but directly into cobalt oxide products, which improves the utilization rate of resources, and also avoids environmental pollution caused by direct discharge of spherical cobalt mother liquor. |
