Abstract

UN PROCESO PARA RECUPERAR PALADIO Y PLATINO PURO A PARTIR DE UN CLORURO ACIDICO SUSTANCIALMENTE IMPURO, LIBRE DE ORO Y DE BASE METALICA, O UNA DISOLUCION MEZCLADA DE SULFATO/CLORURO; DICHO PROCESO COMPRENDE LOS PASOS DE: CONTACTAR LA DISOLUCION ACIDICA DE PH MENOR DE 1.5 CON UNA DISOLUCION ORGANICA QUE COMPRENDE UN DISOLVENTE 8-HIDROXI QUINOLINA, UN REACTIVO DE EXTRACCION, UN MODIFICADOR DE FASE Y UN DILUYENTE AROMATICO PARA EXTRAER SIMULTANEAMENTE PLATINO Y PALADIO DE LA DISOLUCION ORGANICA. DEPURAR LA DISOLUCION ORGANICA CARGADA PARA ELIMINAR LAS IMPUREZAS Y EL ACIDO. EXTRAER LA CARGA ORGANICA CON UN DISOLUCION TAMPON QUE OPERA EN UN PH DE 1-5 A 20 -50 C PARA RECUPERAR SELECTIVAMENTE EL PLATINO. EXTRAER LA CARGA ORGANICA LIBRE DE PLATINO CON UN ACIDO 3-8 UN CLORHIDRICO PARA RECUPERAR EL PALADIO Y REGENERAR LA DISOLUCION ORGANICA LAVANDOLA CON AGUA.
