Abstract

a. Procédé d'enrichissement et de solubilisation des phosphates contenus dans les scories d'aciérie. b. On ajoute, à une scorie d'aciérie en fusion ou encore très chaude, des porteurs de phosphore sous la forme de phosphates partiellement ou totalement désagrégés ou de mélanges usuels pour la fabrication de phosphate calciné, ce qui provoque l'enrichissement de la scorie en acide phosphorique et en même temps la conversion des composés de phosphore insolubles en composés solubles dans les plantes. c. Application à la valorisation des scories des procédés de traitement de fontes pauvres en phosphore.
