natural zeolite comminuting

What is the major difference between natural and synthesis zeolites?Natural zeolites have many more chemical elements in its structure that synthetic zeolites. Therefore, it is said that the synthetic zeolites are purer than natural zeolites. Natural zeolites are found in many geological environments and they have much greater structural and crystalchemical variability than synthetic zeolites.natural zeolite comminuting,EP0002960A1 - Manufacture of zeolite A crystals of uniformly small .in the manufacture of zeolite A crystals, characterized by a size in the range of about 1 to about 10 µm (micrometers or microns) the crystal size is controlled to within the range of ± 1µm by seeding a sodium aluminum silicate gel that is free of nucleating particles with a predetermined number of comminuted zeolite A crystals.

Oct 1, 2003 . Several toxicological studies of a natural zeolite named clinoptilolite proved that this compound is non-toxic and safe for use in human and veterinary medicine. Recent experiments in vitro and in vivo have suggested that clinoptilolite could be used as an adjuvant in anticancer therapy (Pavelic et al., 2001).
