Abstract

Un método de lixiviación en pilas de cobre de un mineral, dicho método incluye al menos un paso de reposo seguido por un paso irrigación, caracterizado porque, durante el paso de irrigación una solución de lixiviación que contiene iones cloruro se aplica al mineral a una velocidad más alta que durante el paso de reposo.
