Abstract

Esta invención se refiere a un proceso para la recuperación de metal/es precioso/s de un material que contiene metal/es precioso/s en una suspensión o solución de lixiviación acuosa. El proceso incluye el paso de poner en contacto el/los metal/es precioso/s en la suspensión o solución de lixiviación con un ligando seleccionado entre ditiooxamida (ácido rubeánico), o una ditiooxamida sustituida. La lixiviación de PGMs, oro y plata de sus minerales utilizando el ligando de la presente invención puede llevarse a cabo bajo condiciones alcalinas acuosas, evitando tanto condiciones ácidas corrosivas como el uso de cianuro.
