Abstract

Un pre-tratamiento de menas de óxido que contienen metales preciosos, antes de la Iixiviación de metales preciosos por tiosulfato. El proceso comprende mezclar la mena de óxido en agua que se ha oxigenado en la presencia de un material a base de carbono (por ejemplo, carbono activado u otro tipo de carbono). El material a base de carbono puede separarse del barro de la mena, y el oro posteriormente se Iixivia mediante un Iixiviante tiosulfato. Reivindicación 20: Un proceso caracterizado porque comprende: contactar un material que contiene oro con carbono y un oxidante para formar un barro pre-tratado; separar el carbono del barro pre-tratado para formar un barro agotado en carbono; y contactar el barro agotado en carbono con tiosulfato para Iixiviar oro del material pre-tratado que contiene oro, donde: en la etapa de contacto, el material que contiene oro está sustancialmente libre de contacto con tiosulfato; el material que contiene oro contiene más óxidos que sulfuros; el material que contiene oro es una mena de óxido que es susceptible a la recuperación de oro por cianuración y que es refractaria al tiosulfato; el oxidante es oxígeno molecular; el barro antes del pre-tratamiento mediante contacto del material que contiene oro con carbono y un oxidante tiene un pH de al menos aproximadamente pH 3; durante el contacto del material que contiene oro con carbono y un oxidante, el barro tiene un pH desde aproximadamente pH 7 hasta aproximadamente pH 10; durante el contacto del material que contiene oro con carbono y un oxidante, el barro tiene un potencial de oxidación-reducción que oscila desde aproximadamente 100 hasta aproximadamente 750 mV (electrodo de Ag/AgCI); una tasa de contacto de oxigeno molecular con el barro durante el contacto del material que contiene oro con carbono y un oxidante es de al menos 0,10 L de O₂/L de barro/min.; y una proporción en peso del material que contiene oro respecto al carbono que oscila desde aproximadamente 1:3 hasta aproximadamente 1:0,01.
