ABSTRACT OF THE DISCLOSURE A process is disclosed for the preparation of bleach catalysts in aggregate form. The steps comprise adsorbing a manganese (II) salt onto an aluminosilicate support, granulating with a high disrupting force an aqueous slurry of the aluminosilicate bearing manganese (II), and drying the resultant aggregates. At least 70% of the dried aggregates resulting from the process must have a diameter size from at least 250 to 2000 microns.
