Abstract

Process for granulating ammonium nitrate, in particular granulation of aqueous solutions of high concentration, characterized in that to the ammonium nitrate solutions are added, in any state of its preparation one or several natural magnesium metasilicates of fibrous structure and/or laminate, or its equivalents obtained by synthesis, in proportions that can vary between 0.01% and 10%, chosen preferably between 0.1% and 5% in the presence, if necessary, of very small quantities of a wetting product convenient.
