Abstract
Un método para la recuperacion de cobre de un concentrado de sulfuro de cobre que comprende una sulfosal de arsénico de cobre o una sulfosal de antimonio de cobre, usando carbono como catalizador. El concentrado y el carbono se agregan a una solucion de lixiviacion ácida de sulfato. El cobre es lixiviado del concentrado, en presencia de un gas que contiene oxígeno. El potencial de operacion se mantiene sobre un nivel seleccionado. La relacion de carbono:sulfuro de cobre, del carbono agregado al sulfuro de cobre presente en el concentrado agregado es por lo menos 1:20. El carbono puede mantenerse sobre una concentracion seleccionada en la solucion de lixiviacion. El cobre lixiviado es recuperado de la solucion por métodos convencionales.
