| titleOfInvention | Electrolytic metal manganese waste residue treatment method |
| abstract | The invention relates to a method for treating electrolytic manganese metal waste residue, which comprises the following steps: A. limestone is roasted to obtain quicklime and carbon dioxide; B. electrolytic metal manganese waste residue is slurried, leached, lime powder is added, and ammonia gas is recovered; the pH of the solution is adjusted to 6.0-6.4, Remove iron oxide, filter press to obtain filter press block A and filter press A, wash filter press block A with water and filter press to obtain filter press block B and filter press B; adjust the pH of filter press A to 11.5-12, filter press, Obtain filter press block C and press filtrate C; C. add silicon dioxide, calcium oxide, alumina, iron oxide in filter press block B, dry, pre-decompose, calcine to obtain cement clinker; D. filter press block C Slurrying, leaching, adjusting pH to 6.0‑6.4, removing impurities, standing, and pressure filtration to obtain filter press block D and pressure filtrate D, adding ammonia water to pressure filtrate D to adjust pH to 8.8‑9, and continuing to add ammonia solution to adjust pH to 11.4‑11.8. The method realizes the recycling and reuse of resources. |
