| titleOfInvention | Separation purification of zinc and manganese from zinc-manganese solution |
| abstract | A novel method is disclosed for preparing a purified zinc sulfate solution, which is an intermediate material for preparing zinc sulfate monohydrate for use as a feed additive from a zinc manganese solution derived from waste batteries. The present invention is a method of separating and purifying zinc and manganese from a raw material powder containing zinc oxide, manganese oxide, and manganese dioxide, comprising: (a) filtering and removing manganese dioxide (MnO 2) precipitated by reacting the raw material powder with sulfuric acid. ; (b) filtering and removing the precipitated manganese hydroxide (Mn(OH) 2 ) by back-leaching the filtrate of step (a) with caustic soda; (c) precipitating and separating zinc hydroxide (Zn(OH) 2 ) by adjusting the pH of the filtrate of step (b); And (d) reacting the separated zinc hydroxide with sulfuric acid to obtain a purified zinc sulfate solution. |
