Abstract
Processes for recovering colloids of carboxylate ligand modified ferric iron hydroxide materials such as IHAT (Iron Hydroxide Adipate Tartrate) are described based on the use of water miscible non-aqueous solvents, such as ethanol, methanol and acetone. The processes produce materials with advantageous properties such as improved bioavailability, reduced aggregation and/or agglomeration and/or increased iron content.
