Abstract

Un material mineral que contiene metales preciosos es sometido a una lixiviación ácida con tiocianato para disolver los metales preciosos en la forma de complejos de metales preciosos-tiocianato. La alimentación de solución de lixiviación de tiocianato puede incluir una relación molar alta de hierro férrico a tiocianato. Los metales preciosos se pueden separar de la solución de lixiviación de tiocianato prenada, tal como por transferencia de metales preciosos de los complejos de metales preciosos-tiocianato a complejos de metales preciosos-cianuro y después cargar los complejos de metales preciosos-cianuro sobre un material absorbente. El cianuro restante en la solución de lixiviación de tiocianato puede ser convertido en tiocianato para una lixiviación adicional de metales preciosos.
