| titleOfInvention | Recovery of Fe and AI from P-containing materials |
| abstract | Phosphorus-containing materials are treated with inorganic acids to form leach solutions (7) containing trivalent iron, trivalent aluminum, and phosphorus. Iron and / or aluminum is extracted by adsorption in a capture substance (22) affinity for cations and by releasing iron and / or aluminum into a stripping solution during regeneration. The regeneration is carried out with hydrochloric acid (31). Anionic metal chloride complexes are extracted from the hydrochloric acid-containing stripping solution (32) by adsorption in a capture substance (42) having an affinity for anionic metal chlorides. Metal chlorides are recovered from the charged capture substance (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 if desired. The hydrochloric acid-containing stripping solution (31) is recycled and used for stripping the capture substance (26) loaded with iron and / or aluminum. The depleted ash slurry solution (9) is treated for phosphorus recovery and is preferably reused for dissolving a phosphorus-containing material. (Fig. 2) |
