Abstract

Se refiere a un metodo de recuperacion de oro a partir de una solucion concentrada de cloruro de cobre que contiene oro que comprende: a) una etapa de electrodeposicion, en la que se aplica un potencial externo o una corriente reductora a un electrodo contenido en la solucion concentrada de cloruro de cobre que contiene oro, depositando asi cobre y opcionalmente oro en el electrodo, b) una etapa de reemplazo redox, en la que en la etapa a) el potencial externo o la corriente reductora aplicada se corta o se reduce, lo que permite que el cobre depositado en el electrodo se reemplace espontaneamente por el oro contenido en la solucion, obteniendo asi un electrodo que contiene oroIt refers to a method of recovering gold from a concentrated solution of copper chloride containing gold that comprises: a) an electroplating step, in which an external potential or a reducing current is applied to an electrode contained in the concentrated solution of copper chloride containing gold, thus depositing copper and optionally gold on the electrode, b) a redox replacement stage, in which in stage a) the external potential or the applied reducing current is cut or reduced, which allows the copper deposited on the electrode to be spontaneously replaced by the gold contained in the solution, thus obtaining an electrode containing gold
