Abstract

PROCEDIMIENTO DE OBTENCION DE FLUORURO DE HIDROGENO A PARTIR DE MINERALES QUE CONTIENEN FLUORURO. SE PONE EN CONTACTO UN MINERAL DE ESPATO DE FLUOR CON MINERALES QUE CONTIENEN FLUORURO Y FOSFATO, TALES COMO FOSFATO DE CALCIO O FLUOROAPATITO, Y CON ACIDO FLUOROSULFONICO PARA LIBERAR FLUORURO DE HIDROGENO Y COMPUESTOS DE FOSFORO VOLATILES, TALES COMO PENTAFLUORURO DE FOSFORO, OXIFLUORURO DE FOSFORO O ACIDOS FLUOROFOFORICOS. SE SEPARA EL FLUORURO DE HIDROGENO Y LOS COMPUESTOS DE FOSFORO VOLATILES DEL FLUOROSULFONICO EN EXCESO Y LA MATERIA RESIDUAL. SE SEPARA EL FLUORURO DE HIDROGENO DE LOS COMPUESTOS DE FOSFORO VOLATILES Y SE RECUPERA EL MISMO.
