Abstract
Un método para lixiviar cobre a partir de una pila de mena. Dicho método incluye al menos una etapa de reposo seguida de un paso de irrigación, en donde, durante el paso de irrigación, una solución de Iixiviación que contiene iones cloruro se aplica a la mena a una tasa superior a la aplicada durante la etapa de reposo.A method to leach copper from a pile of ore. Said method includes at least one resting stage followed by an irrigation step, wherein, during the irrigation step, a leaching solution containing chloride ions is applied to the ore at a higher rate than that applied during the resting stage. .
