Abstract

SE HACE REACCIONAR ACIDO FLUOSILICICO CON PIEDRA DE FOSFATO PARA PRODUCIR ACIDO FOSFORICO DE PROCESAMIENTO EN ESTADO HUMEDO Y FLUORURO DE CALCIO QUE SE HACE REACCIONAR POSTERIORMENTE CON ACIDO SULFURICO PARA PRODUCIR FLUORURO DE HIDROGENO Y SULFATO DE CALCIO. EL FLUORURO DE HIDROGENO ES DESPOJADO ENTONCES DEL ACIDO FOSFORICO Y SE RECUPERA TANTO COMO FLUORURO DE HIDROGENO ANHIDRIDO O COMO ACIDO HIDROFLUORICO CONCENTRADO O SE HACE REACCIONAR CON TRIHIDRATO DE ALUMINIO PARA PRODUCIR FLUORURO DE ALUMINIO; CON CARBONATO DE SODIO PARA PRODUCIR FLUORURO/BIFLUORURO DE SODIO; O CON AMONIACO PARA PRODUCIR FLUORURO/BIFLUORURO DE AMONIO.
