Recycling method of ammonium sulfate |
| abstract |
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recycling an ammonium sulfate waste solution, and more particularly, to a method for recycling an ammonium sulfate waste solution which obtains ammonium sulfate having a high purity from an ammonium sulfate waste solution generated in a lithium secondary battery production process, . A method for recycling an ammonium sulfate waste solution according to the present invention comprises the steps of removing an impurity contained in an ammonium sulfate waste solution (S100) and a solid-liquid separation step (S100) of obtaining an ammonium sulfate solid residue by subjecting an ammonium sulfate- S200) and a crystallization step (S300) for crystallizing the ammonium sulfate solid residue. |
