Abstract

Un método y una disposición para separar arsénico y, opcionalmente, antimonio, de un material de partida que comprende: un paso de lixiviación de bajo contenido de ácidos para lixiviar una primera parte de hierro, arsénico, cobre y, opcionalmente, antimonio, hacia la primera solución de lixiviación, un primer paso de separación de sólido-líquido, en donde un primer residuo sólido de lixiviación se separa de la primera solución de lixiviación, un paso de lixiviación de alto contenido de ácidos para lixiviar una segunda parte de hierro, arsénico, cobre y, opcionalmente, antimonio, hacia la segunda solución de lixiviación, un segundo paso de separación. de sólidos-líquido para obtener un segundo residuo sólido de lixiviación y la segunda solución de lixiviación se recicla de regreso hacia el paso de lixiviación de bajo contenido de ácidos, un paso de precipitación para obtener un precipitado que comprende arseniato férrico y, opcionalmente, compuestos de antimonio, y un tercer paso de separación de sólido-líquido, en donde la solución que comprende cobre se separa del precipitado obtenido. La disposición comprende una unidad de lixiviación de bajo contenido de ácidos, una primera unidad de separación sólido-líquido, una unidad de lixiviación de alto contenido de ácidos, una segunda unidad de separación de sólido-líquido, una unidad de precipitación y una tercera unidad de separación sólido-líquido.A method and arrangement for separating arsenic and, optionally, antimony, from a starting material comprising: a low acid leaching step to leach a first part of iron, arsenic, copper and, optionally, antimony, into the first leaching solution, a first solid-liquid separation step, wherein a first solid leaching residue is separated from the first leaching solution, a high acid leaching step to leach a second part of iron, arsenic , copper and, optionally, antimony, towards the second leaching solution, a second separation step. of solid-liquid to obtain a second solid leaching residue and the second leaching solution is recycled back to the low acid leaching step, a precipitation step to obtain a precipitate comprising ferric arsenate and, optionally, compounds of antimony, and a third solid-liquid separation step, wherein the solution comprising copper is separated from the precipitate obtained. The arrangement comprises a low acid leaching unit, a first solid-liquid separation unit, a high acid content leaching unit, a second solid-liquid separation unit, a precipitation unit and a third unit solid-liquid separation.
