Abstract
Esta invención se relaciona con un método para recuperar valores de metales tales como oro, cobre, níquel, zinc y uranio a partir de minerales que contienen dichos valores de metales. El método incluye los pasos de triturar un mineral (10) para proporcionar una arena que contiene valores de metales con un P80 de menos de 5 mm pero mayor a 1 mm; clasificar la arena (12) para extraer una fracción más fina para proporcionar arena clasificada con un P10 de más de 0,15 mm, y una relación P90/P10 de menos de 25 y mayor a 3, formar una pila (18) a partir de la arena clasificada, y distribuir el lixiviante y el aire a través de la pila para lixiviar los valores de la arena en un lixiviado preñado, a partir del cual se pueden recuperar los valores lixiviados. La invención también se relaciona con una pila formada a partir de mineral procesado por medio de este método.
