Abstract

Un método de lixiviación en pilas de un metal a partir de un material ROM que contiene un material que contiene sulfuro metálico, como un mineral que contiene sulfuro de cobre. El método comprende formar una pila del material ROM o extender un pila existente agregando el material ROM a la pila. El método también comprende lixiviar el metal del material ROM en la pila con una solución de lixiviación ácida y producir una solución de lixiviación cargada que contiene el metal en solución y recuperar metal de la solución de lixiviación cargada. La pirita que ya se encuentra en el material ROM genera ácido y calor que facilita la lixiviación del metal del material ROM. El material ROM se puede transferir directamente desde la mina a la pila sin cambiar el tamaño de las partículas de material en el material ROM. El método puede comprender agregar pirita adicional y otros aditivos para facilitar la lixiviación del metal.
