METHOD FOR EFFLUENT TREATMENT IN SMELTING OF NICKEL OXIDE ORE |
| 摘要 |
The present invention aims at providing a method for effluent treatment, which enables the separation and recovery of a high-density and high-concentration aluminum sediment from waste water that is discharged in the smelting of a nickel oxide ore and contains aluminum ions. In the present invention, an alkali and an iron-containing solid are added to waste water containing aluminum ions to form a slurry, and the slurry is allowed to stand to perform solid-liquid separation, whereby an aluminum sediment and an effluent is formed. |
