Abstract

PROCEDIMIENTO DE FABRICACION DE ACIDO FOSFORICO.SE ATACA CON UN ACIDO UN MINERAL DE FOSFATO Y SE OBTIENE UNA PRIMERA PAPILLA. SE FILTRA ESTA PAPILLA, SE CONCENTRA EL ACIDO FILTRADO Y SE CONDENSAN LOS VAPORES PROCEDENTES DE LA CONNCENTRACION POR CONTACTO CON UN LIQUIDO ABSORBENTE Y SE RECUPERA UNA SOLUCION DE ACIDO FLUOSILICICO Y SE ATACA, ADEMAS, MINERAL DE FOSFATO CON DICHA SOLUCION DE ACIDO FLUOSILICICO Y EN PRESENCIA DE UNA PARTE DEL ACIDO FOSFORICO OBTENIDO DESPUES DE LA FILTRACION DE LA PRIMERA PAPILLA. SE OBTIENE UNA SEGUNDA PAPILLA, SE FILTRA ESTA SEGUNDA PAPILLA, SE SEPARA UN SOLIDO QUE COMPRENDE COMPUESTOS DE FLUOR Y DE SILICE, ESENCIALMENTE EN FORMA DE CASIF6, Y CON LA SEGUNDA PARTE DEL ACIDO OBTENIDO DESPUES DE LA FILTRACION DE LA PRIMERA PAPILLA.
