Abstract
PROCEDIMIENTO PARA LA RECUPERACION DE COMPOSICIONES SOLIDAS QUE LO CONTIENE CONJUNTAMENTE CON OTROS COMPUESTOS METALICOS. SE TRATA A LAS COMPOSICIONES QUE CONTIENEN EL MOLIBDENO CON UNA SOLUCION ACUOSA DE HIDROXIDO DE METAL ALCALINO, HIDROXIDO SODICO, CON EL FIN DE SOLUBILIZAR EL MOLIBDENO AL CONVERTIRLO EN UN MOLIBDATO DE METAL ALCALINO. SE SEPARA POR FILTRACION EL RESIDUO SOLIDO OBTENIDO. SE TRATA LA SOLUCION ACUOSA CON RESINA DE INTERCAMBIO CATIONICO FUERTE PARA CONVERTIR DICHO MOLIBDATO EN ACIDO MILBDICO. DICHA RESINA TIENE UNA MATRIZ FORMADA POR POLIESTIRENO RETICULADO CON DIVINILBENCENO. POR ULTIMO SE RECUPERA LA SOLUCION ACUOSA RESULTANTE DE ACIDO MOLIBDICO. ES APROPIADO PARA USARSE EN LA RECUPERACION DEL MOLIBDENO A PARTIR DE CATALIZADORES AGOTADOS, EN ESPECIAL LOS USADOS PARA LA OXIDACION DE METANOL A FORMALDEHIDO.
