Recovery of al from p-containing material |
| abstract |
Phosphorus containing material is treated with mineral acid to form a leach-solution (7) comprising of trivalent aluminum, phosphorus and optionally trivalent iron. Aluminum and possibly iron is extracted by adsorbing in a scavenger (22) having an affinity for cations and by releasing aluminum and iron into a strip-solution during regeneration. The regeneration is performed with hydrochloric acid (31). Anionic metal chloride complexes are extracted from the hydrochloric acid strip-solution (32) by adsorbing in a scavenger (42) having affinity for anionic metal chlorides. Metal chlorides are recovered from the loaded scavenger (46) by elution with water (49). Gaseous hydrogen chloride (38) is added to the raffinate (33) from the metal chloride extraction. Crystalline aluminum chloride hexahydrate (37) is separated. The hydrochloric acid strip-solution (31) is recycled and used for stripping a scavenger (26) loaded with aluminum and/or iron. The depleted ash leach-solution (9) is treated for phosphorus recovery and preferably reused for dissolution of a phosphorus containing material. |
