Abstract
El propósito de esta investigación fue analizar cómo el tiempo de tratamiento y el porcentaje de etanol afectan el proceso de desorción, con el objetivo de mejorar la extracción de oro y plata del carbón cargado.
El estudio se realizó variando los parámetros operativos de desorción para las cosechas de una planta ADR. Se utilizó un diseño experimental de 22 con 2 réplicas, usando como variables independientes el tiempo de tratamiento y el porcentaje de etanol en volumen. La variable respuesta fue el % de extracción de oro y plata. Se trabajó con niveles de tiempo de tratamiento de 12, 24, 36 y 38 horas, y porcentajes de etanol de 15%, 18% y 20%. Mediante el análisis comparativo factorial, se encontró que la mayor extracción de oro y plata se logró con un tiempo de tratamiento de 38 horas y un porcentaje de etanol del 20%, obteniéndose una extracción máxima de 0.043 g Au/kg de carbón y 0.064 g Ag/kg de carbón.
The purpose of this research is to analyze how treatment time and ethanol percentage affect the desorption process, with the aim of improving the extraction of gold and silver from loaded carbon. The study was carried out by varying the desorption operating parameters for the harvests of an ADR plant, using a 22 model (two independent variables) with 2 replicates. The independent variables were the treatment time and the volume percentage of ethanol, while the response variable was the extraction of gold and silver. For this thesis, treatment time levels of 12 h, 24 h, 36 h and 38 h, and ethanol percentages of 15%, 18% and 20% were used. Through a comparative factorial analysis, it was found that the highest extraction of gold and silver was achieved with a treatment time of 38 h and an ethanol volume percentage of 20%, obtaining a maximum extraction of 0.043 g Au/kg carbon and 0.064 g Ag/kg carbon.
