Abstract

Un método para controlar el equilibrio ácido en un proceso de lixiviación en pilas de cloruro alto para maximizar la disolución de cobre en una etapa de curado y para aumentar la recuperación general de cobre que incluye una etapa de aglomeración en la que las soluciones de proceso y ácido se combinan con el mineral antes del apilamiento para formar una pila seguida mediante una fase de curado para lixiviar una porción del cobre en el mineral en la pila seguido de una fase de lixiviación irrigada en la que los minerales de cobre restantes se lixivian y el cobre se recupera de una solución de lixiviación preñada mediante un paso de extracción con disolvente seguido de un paso de electrodeposición en el que la concentración de ácido en la solución de lixiviación previa que informa a la etapa de extracción con solvente es inferior a 10 g/L para permitir la recuperación efectiva de cobre de la solución de lixiviación preñada en la etapa de extracción por solvente.
