Abstract

Procedimiento para la elaboración de un residuo que contiene cromato y vanadato, al objeto de separar el cromato del vanadato, caracterizado porque al residuo se añade un material que contiene dióxido de titanio; el residuo se somete a descomposición oxidativa en presencia de un álcali, a una temperatura de 600 a 1.200ºC; y el cromato se separa del vanadato.
