Abstract

La presente invención describe un procedimiento nuevo para lixiviar minerales sulfurados que consiste en la lixiviación de mena triturada en un reactor de cuba, en donde la solución de lixiviación se alimenta con un valor de ORP cercano al límite superior adecuado para la lixiviación y la solución de lixiviación de salida sale del reactor con un ORP mayor que el límite superior adecuado para la lixiviación de la mena. La solución de lixiviación de salida que sale del reactor de lixiviación pasa por una etapa de oxidación de hierro fuera del reactor de lixiviación, produciendo la oxidación del hierro sulfato férrico soluble que se mezcla con una parte recirculada de la solución de lixiviación de salida, para aumentar su ORP hasta un valor cercano al límite superior del intervalo del potencial rédox que es adecuado para la lixiviación de la mena.
