Abstract

Revela un método para separar arsénico y opcionalmente antimonio a partir de un material de partida que comprende cobre, arsénico y opcionalmente hierro y antimonio, donde el método comprende - una etapa de lixiviación de ácido débil, en el que el material de partida se pone en contacto bajo presión atmosférica con una primera solución de lixiviación que comprende ácido sulfúrico para lixiviar una primera parte de cobre, arsénico, y si está presente hierro y antimonio en la primera solución de lixiviación, - una primera etapa de separación sólido - líquido, en la que un primer residuo de lixiviación sólido se separa de la primera solución de lixiviación, - una etapa de lixiviación ácida fuerte, en la que el primer residuo de lixiviación sólido se pone en contacto a presión atmosférica y condiciones de oxidación con una segunda solución de lixiviación que comprende ácido sulfúrico para lixiviar una segunda parte de cobre, arsénico y si está presente hierro y antimonio en la segunda solución de lixiviación, - una segunda etapa de separación sólido-líquido, en la que se separa un segundo residuo de lixiviación sólido de la segunda solución de lixiviación y se recicla la segunda solución de lixiviación a la etapa de lixiviación con contenido de ácido débil, - una etapa de precipitación, en la que la primera solución de lixiviación que comprende cobre, arsénico y si está presente hierro y antimonio obtenidos de la primera etapa de separación sólido - líquido, se pone en contacto con un agente precipitante para obtener un precipitado que comprende arseniato férrico y opcionalmente compuestos de antimonio, - una tercera etapa de separación sólido - líquido, en la que la solución que comprende cobre se separa del precipitado obtenido. Además se revela una disposición para llevar a cabo dicho método la cual no está claramente definida como se indica arriba.It reveals a method for separating arsenic and optionally antimony from a starting material comprising copper, arsenic and optionally iron and antimony, where the method comprises - a weak acid leaching step, in which the starting material is placed in contact under atmospheric pressure with a first leaching solution comprising sulfuric acid to leach a first part of copper, arsenic, and if iron and antimony is present in the first leaching solution, - a first solid-liquid separation stage, in the that a first solid leaching residue is separated from the first leaching solution, - a strong acid leaching step, in which the first solid leaching residue is contacted at atmospheric pressure and oxidation conditions with a second leaching solution comprising sulfuric acid to leach a second part of copper, arsenic and if present iron and antimony in the second leaching solution, - a second solid-liquid separation stage, in which a second solid leaching residue is separated from the second leaching solution and the second leaching solution is recycled to the leaching stage with weak acid content, - a precipitation stage, in which the first leaching solution comprising copper, arsenic and if iron and antimony obtained from the first solid-liquid separation stage is present, is contacted with an agent precipitant to obtain a precipitate comprising ferric arsenate and optionally antimony compounds, - a third step of solid-liquid separation, in which the solution comprising copper is separated from the precipitate obtained. In addition, an arrangement is disclosed for carrying out said method which is not clearly defined as indicated above.
