Abstract
Procedimiento para destinar suspensiones de material fibroso mediante flotación, en el cual la suspensión de material fibroso cargada con aire es incorporada en una celda de flotación, la espuma que se forma sobre la superficie de la suspensión de material fibroso es evacuada junto con las impurezas, y se retira suspensión purificada de material fibroso - material fibroso destinado - , caracterizado porque la suspensión de material fibroso cargad con aire es introducida en la zona superior de una celda de flotación, una parte del material fibroso destinado es retirada como suspensión purificada de material fibroso en la zona de fondo de la celda de flotación y una suspensión de aire/agua se introduce en la celda de flotación en la zona situada por encima del lugar de la retirada de material las fibras descendentes de material fibroso destinado.
