Precious metals such as gold (Au) and silver (Ag) are essential to our modern society due to their unique properties, such as high conductivity and physical and chemical resistance. They are teofn concentrated in by-products during the extraction of base metals. In the present work, a chalcopyrite leaching residue, constituted mainly of elemental sulfur and jarosites, was subjected to different pretreatments and leached with different leaching media to recover Au and Ag. The solid residue was pretreated by desulfurization,peroxidation,desulfurization+peroxidation and leached with cyanide, cyanide+glycine, and glycine. For comparison, samples without pretreatment were also leached using the same leaching media. Changes in the mineralogical species were followed to explain the effects of pretreatment and leaching medium on the dissolution of Au and Ag. Results indicate that the highest extraction of gold and silver (Au:99.50%, Ag:46.71%) is achieved by using a combined desulfurization+peroxidation pretreatment and cyanide as leaching medium.

Los metales preciosos como el oro (Au) y la plata (Ag) son esenciales para nuestra sociedad moderna debido a sus propiedades únicas como alta conductividad, resistencia física y química. A menudo se concentran en subproductos durante la extracción de metales básicos. En el presente trabajo, un residuo de lixiviación de calcopirita constituido principalmente por azufre elemental y jarositas fue sometido a diferentes pretratamientos y lixiviación con diferentes medios de lixiviación para recuperar Au y Ag. El residuo sólido se pretrató mediante desulfuración, peroxidación, desulfuración + peroxidación y se lixivió con cianuro, cianuro + glicina y glicina. A modo de comparación, las muestras sin tratamiento previo, también se lixiviaron utilizando el mismo medio de lixiviación. Se siguieron los cambios en las especies mineralógicas con el fin de explicar los efectos del medio de pretratamiento y lixiviación sobre la disolución de Au y Ag. Los resultados indican que la mayor extracción de oro y plata (Au: 99,50%, Ag: 46,71%) se logra mediante el uso de un pretratamiento combinado de desulfuración + peroxidación y cianuro como medio de lixiviación.
