Abstract

L'invention concerne une méthode de préparation d'une suspension aqueuse d'au moins un matériau phosphaté comprenant la dispersion dans de l'eau de particules de matériau phosphaté en présence d'au moins un additif de type polymère anionique d'acide acrylique ou d'acide méthacrylique. La suspension selon l'invention a une viscosité inférieure à 1 500 mPa.s. L'invention concerne également le conditionnement du matériau phosphaté associé au polymère anionique, pour son traitement ultérieur au moyen d'au moins un acide fort, pour la préparation industrielle d'acide phosphorique.
