| description | In this paper, we have sought to identify the conditions and optimal operating variables for the processing of a gold ore, in such a way to achieve high efficiency in the recovery of the precious metal. Initially a characterization of the mineral under study was carried out with the performance of different laboratory tests. Likewise, a grinding test was made. In the same way, a sample of ore was classified using a series of Tyler sieves. Next, the material was subjected to gravimetric concentration on a Wilfley concentrator table. The fines, product of the concentration, with a 100 % granulometry through 170 Tyler meshes, were subjected to conventional flotation tests. In this way, to optimize the recovery of gold from the gold ore under study, an experimental design of 2k factorial analysis with central point, three variables and the response surface method was applied to determine the optimal parameters to achieve an efficient recovery during cyanidation. The results obtained show that the mineral has a high degree of cyanide leachability, obtaining a gold recovery of 89.35 %. The research demonstrated that the statistical experimental design is a valuable tool for the efficient processing of the minerals, since it allows finding the optimal parameters of the cyanidation process such as the leaching time, the granulometry of the mineral and the concentration of NaCN. The results obtained with the application of the statistical design in the cyanidation tests allowed determining the optimal operating conditions for a maximum gold recovery. |

En este trabajo se buscó identificar las condiciones y variables óptimas de operación para el procesamiento de un mineral de oro, de tal forma que se alcanzara una alta eficiencia en la recuperación del metal precioso. Inicialmente se llevó a cabo una caracterización del mineral en estudio con la realización de diferentes ensayos de laboratorio. Igualmente se ejecutó un ensayo de moliendabilidad. A la vez, una muestra de mineral fue clasificada mediante una serie de tamices Tyler. Después, el material fue sometido a concentración gravimétrica en mesa Wilfley. Los finos, producto de la concentración, con una granulometría 100 % pasante 170 mallas Tyler, fueron sometidos a pruebas de flotación convencional. De esta forma, con el fin de optimizar la recuperación del oro del mineral aurífero en estudio, se aplicó un diseño experimental de análisis factorial 2k con punto central, tres variables y el método de superficie de respuesta para determinar los parámetros óptimos con el fin de lograr una recuperación eficiente durante la cianuración. Los resultados obtenidos mostraron que el mineral presenta un alto grado de lixiviabilidad en cianuro, lográndose una recuperación del oro del 89.35 %. De acuerdo con esto, se corroboró que el diseño experimental estadístico es una herramienta valiosa para el procesamiento eficiente de los minerales, dado que permite encontrar los parámetros óptimos del proceso de cianuración, como son el tiempo de lixiviación, la granulometría del mineral y la concentración de NaCN. Los resultados conseguidos con la aplicación del diseño estadístico en las pruebas de cianuración posibilitaron determinar las condiciones óptimas de operación para una máxima recuperación de oro.
