| titleOfInvention | The method reclaiming dilval from nickel ores |
| abstract | The method that the present invention relates to reclaim dilval from nickel ores, including: reduction step, the nickel ores of the reducing gas reduction used containing hydrogen the reduced powder obtained is made serosity under an inert atmosphere, thus prepares the serosity of leaching reduced powder；Leach step, in the serosity of leaching reduced powder, inject sulphuric acid or hydrochloric acid, and dissolve in the form of an ion and leaching nickel and ferrum, thus obtain containing nickel ion and the solution of iron ion；Leach residue removal step, from the solution containing nickel ion and iron ion, remove residue, thus obtain containing nickel ion and the leachate of iron ion；And settling step, following serosity is injected in the solution containing nickel ion and iron ion, i.e. in described serosity, the reduced powder obtained containing the reducing gas reduced nickel Ore containing hydrogen by use of 10 weight % to 40 weight % in leachate, above in regard to precipitation reduced powder and the gross weight of leaching reduced powder, thus with the ferrum of the nickel displacement precipitation reduced powder in the solution containing nickel ion and iron ion coprecipitated nickel hydroxide ferroalloy. |
