Abstract

METODO DE RECUPERAR TUNGSTENO DE TROZOS DE MATERIAL QUE CONTIENE ALEACION DE TUNGSTENO. CONSISTE EN PONER EN CONTACTO LOS TROZOS DE MATERIAL CON UNA SOLUCION ACUOSA ACIDA DE PEROXIDO DE HIDROGENO, QUE OPCIONALMENTE PUEDE CONTENER UN PROMOTOR, EN CUATRO ETAPAS CONSECUTIVAS MANTENIENDO LA TEMPERATURA ENTRE 10 Y 50GC, COMPRENDIENDO CADA ETAPA LOS PASOS DE PONER EN CONTACTO LOS TROZOS CON UNA PARTE DE LA SOLUCION QUE CONTIENE UNA CANTIDAD SUBESTEQUILOMETRICA DE PEROXIDO DE HIDROGENO MANTENIENDO EL CONTACTO HASTA QUE UNA PROPORCION SUSTANCIAL DEL CONTENIDO DE PEROXIDO DE HIDROGENO LIBRE EN LA SOLUCION HA SIDO CONSUMIDA, Y DESPUES DE ESTO SEPARAR LA SOLUCION ENRIQUECIDA EN TUNGSTENO DEL RESIDUO SOLIDO. TIENE APLICACION PARA OBTENER FILAMENTOS DE BOMBILLAS DE LUZ ELECTRICA Y BROCAS DE BARRENAS.
