Abstract

PROCEDIMIENTO PARA RECUPERAR TUNGSTENO DE TROZOS DE MATERIAL QUE CONTIENEN UNA ALEACION DE TUNGSTENO. CONSISTE EN TRAZAR A LOS TROZOS DE ALEACION DE TUNGSTENO CON UNA SOLUCION ACUOSA ACIDA DE PEROXIDO DE HIDROGENO, EN PRESENCIA DE UN BLOQUE FUSIONADO DE UN PRODUCTO DE REACCION, ENTRE 10 Y 50GC Y EN VARIAS ETAPAS, HASTA OBTENER TUNGSTENO EN SOLUCION. LA ALEACION DE TUNGSTENO ES CARBURO DE TUNGSTENO Y EL PROMOTOR SE SELECCIONA ENTRE AMINO-FENOLES Y UN COMPUESTO DE FORMULA (I). SIENDO: A, SUSTITUYENTE HIDROXIDO O AMINO; B, ALDOXINA Y C, ALQUILO, HIDROXIDO O AMINO. SE UTILIZA EN METALURGIA EXTRACTIVA. *FORMULA*
