Abstract

La invencion proporciona un metodo para recuperar oro, el cual permite aumentar la cantidad de oro adsorbido en carbon activado. El metodo para recuperar oro incluye: lixiviar oro en una solucion de lixiviacion acida conteniendo iones de cloruro y/o iones de bromuro como aniones y cobre como cationes para producir un lixiviado de oro; y adsorber oro en el lixiviado de oro en carbon activado, donde el metodo ademas comprende la etapa de ajustar el potencial de oxidacion-reduccion del lixiviado de oro (electrodo de referencia: plata/cloruro de plata) antes de adsorber oro en el lixiviado de oro en el carbon activado para reducir una concentracion de iones de cobre monovalentes en el lixiviado de oroThe invention provides a method for recovering gold, which makes it possible to increase the amount of gold adsorbed on activated carbon. The method of recovering gold includes: leaching gold into an acid leach solution containing chloride ions and / or bromide ions as anions and copper as cations to produce a gold leach; and adsorbing gold in the gold leachate on activated carbon, where the method further comprises the step of adjusting the oxidation-reduction potential of the gold leachate (reference electrode: silver / silver chloride) before adsorbing gold in the leachate of gold in activated carbon to reduce a concentration of monovalent copper ions in the gold leachate
