Abstract

1.- Un método que comprende: poner en contacto una solución que contiene arsénico con un agente fijador en condiciones en las cuales por lo menos una porción del arsénico es fijada por el agente fijador para obtener una solución empobrecida en arsénico y un agente fijador enriquecido en arsénico, donde el agente fijador comprende un compuesto que contiene tierras raras; separar el agente fijador enriquecido en arsénico de la solución empobrecida en arsénico; y, separar un metal recuperable de la solución que contiene arsénico o de la solución empobrecida en arsénico o de ambas. 2.- El método de la reivindicación 1, que además comprende: poner en contacto un material portador de arsénico con un agente lixiviador de arsénico para formar la solución que contiene arsénico y sólidos empobrecidos en arsénico; separar los sólidos empobrecidos en arsénico de la solución que contiene arsénico. 3.- El método de cualquiera de las reivindicaciones 1 y 2, en el que el compuesto que contiene tierras raras comprende dióxido de cerio, en el que la solución empobrecida en arsénico comprende arsénico en una cantidad de menos de alrededor de 20 ppm, y en el que la solución que contiene arsénico se pone en contacto con el agente fijador fluyendo la solución que contiene arsénico a través de un lecho del agente fijador. 4.- El método de cualquiera de las reivindicaciones 1 y 2, en el que el metal recuperable comprende un metal del Grupo lA, Grupo IIA y metales de transición, y en el que el metal recuperable se recupera mediante electrolisis o precipitación o ambas.
