Abstract

La invención se refiere a un método para la precipitación de arsénico y metales pesados a partir de agua ácida, que comprende una fase (II) del método de precipitación con una etapa de precipitación en donde se precipita conjuntamente arsénico y por lo menos un metal pesado primario, en donde un agente precipitador de sulfuro se añade al agua de proceso. La fase (II) del método de precipitación comprende una etapa de acondicionamiento que se lleva a cabo antes de la etapa de precipitación.
