Abstract
Disclosed is a combined treatment method for laterite nickel ore hydrometallurgical slag and phosphating slag, the combined treatment method includes uniformly mixing a laterite nickel ore hydrometallurgical slag, a phosphating slag, and a sodium alkaline salt to obtain a mixed material; subjecting the mixed material to sodium reduction roasting to obtain a roasted material; leaching the roasted material with water and filtering to obtain a water leaching solution and a water leaching slag; subjecting the water leaching slag to magnetic separation to obtain an iron concentrate. In the disclosure, by mixing a laterite nickel ore hydrometallurgical slag and a phosphating slag and then performing sodium reduction roasting, the iron exists in the form of FeOand elements such as manganese and zinc exist in the slag in the form of oxides, and during the roasting process, aluminum oxides react with alkali to be converted into sodium aluminate.
