Abstract

Procedimiento para la depuración de soluciones en circulación en el ciclo de ataque alcalino de la bauxita, en particular para el tratamiento de una solución alcalina de aluminato de sodio del ciclo de ataque alcalino de una bauxita con vistas a la obtención de alúmina hidratada, caracterizado porque se toma una cantidad de dicha solución que contiene un cantidad de carbonato de sodio al menos igual a la cantidad que ha sido puesta en solución durante el ataque, se añade a esta solución una cantidad reciclada de un compuesto del bario inferior a la cantidad que correspondería a la precipitación completa del carbonato de sodio, se separa el precipitado carbonato de bario formado y una solución de aluminato de sodio empobrecida en carbonato de sodio que se reintroduce en el ciclo de ataque alcalino de la bauxita, se calcina el precipitado y se recicla el compuesto del bario que resulta de la calcinación.
