Abstract

L'invention concerne une méthode de préparation industrielle de l'acide phosphorique à partir d'une suspension aqueuse comprenant de l'eau et des particules d'au moins un matériau phosphaté dispersées en présence d'au moins un additif de type polymère anionique. L'acide phosphorique est obtenu par traitement de cette suspension au moyen d'au moins un acide fort. Le polymère est obtenu par réaction de polymérisation d'au moins un acide choisi parmi l'acide acrylique, l'acide méthacrylique et leurs sels. L'invention concerne la mise en œuvre de ce polymère anionique ainsi que la méthode d'amélioration de la rhéologie de la suspension et de l'hydrodynamique du milieu réactionnel siège des réactions de fabrication d'acide phosphorique.
