Abstract

Se describe un método para remover yeso de un material que contiene calcio, donde el método comprende enfriar una solución de lixiviación cargada que contiene calcio (10) poniendo en contacto indirectamente la solución de lixiviación cargada que contiene calcio (10) con una solución de lixiviación cargada agotada en yeso (11) para obtener una solución de lixiviación cargada enfriada (19). La solución de lixiviación cargada enfriada (19) se enfría en un dispositivo de enfriamiento (13) para obtener una solución de lixiviación cargada enfriada adicional (12). El yeso se precipita a partir de la solución de lixiviación cargada enfriada adicional (12) para obtener la solución de lixiviación cargada agotada en yeso (11).
