| titleOfInvention | Removal of ferric iron as hematite under atmospheric pressure |
| abstract | A process for removing ferric iron as hematite under atmospheric pressure from a nickel solution containing ferric and ferrous iron is provided. A process for removing ferric ions as hematite from a nickel solution containing ferric ions and ferrous ions, comprising the following steps: iv) The temperature of the nickel solution is increased from 90 ° C to high Increasing the boiling point of the solution at atmospheric pressure; v) increasing the pH of the nickel solution to 2-3; and vi) adding hematite seeds to promote hematite precipitation (this When ferric ions are precipitated mainly in the crystalline form as hematite).
