Abstract

Un procedimeinto de fabricación de abonos complejos que comprende al ataque de fosfato de cal natural por una mezcla de ácido nítrico y de ácido sulfúrico y la neutralización por amoniaco gaseaso de la pasta así obtenida procedimiento caracterizado porque se realizan el ataque y la neutralización entre 70 y 110º C realizando una circulación forzada y en extreno rápida de la masa de tal manera que el sulfato de calcio formado durante el ataque sólo se hidrata después de terminada la neutralización es decir durante la granulación y la desecación.
