Abstract
EL PROCESO DE TRATAMIENTO DE LOS REVESTIMIENTOS REFRACTARIOS USADOS IMPREGNADOS DE PRODUCTOS FLUORADOS Y DE CIANUROS ALCALINOS QUE COMPRENDE UNA TRITURACION DE LOS REVESTIMIENTOS REFRACTARIOS PREVIAMENTE MACHACADOS EN PRESENCIA DE CAL, LA PUESTA EN SUSPENSION EN MEDIO ACUOSO DE LOS PRODUCTOS ASI TRITURADOS PARA PRECIPITAR EL FLUJO EN FORMA DE CAF SUB 2 CON LIBERACION DE SOSA, Y DESPUES EL CALENTAMIENTO DE LA SUSPENSION A UNA TEMPERATURA T > 140 C EN PRESENCIA DE ARCILLA PARA FORMAR TRAS FIJACION DE LA SOSA LIBRE DE LOS COMPUESTOS DE SINTESIS INSOLUBLES DEL TIPO FELDESPATOIDE O ZEOLITA, Y POR FIN LA SEPARACION POR FILTRACION DE LA FASE SOLIDA RESULTANTE QUE PUEDE DESCARGARSE, DE LA FASE LIQUIDA QUE SE RECICLA PARA FORMAR EN PARTICULAR UNA NUEVA SUSPENSION DE REVESTIMIENTO REFRACTORIO TRITURADO.
