Abstract
Procedimiento para la flotación de contaminantes a partir de una suspensión acuosa de materias fibrosas (S), en que se generan burbujas de gas (1) en un líquido, con ayuda de las burbujas de gas (1) se forma una espuma (2) que asciende en contra del campo de gravedad, se acumulan los contaminantes sobre las burbujas de gas (1) y se evacuan los contaminantes junto con las burbujas de gas (1) en una espuma de flotación (2), caracterizado porque la suspensión de materias fibrosas (S) es adicionada a la espuma (2), es conducida en contra del sentido de ascensión de la espuma (2) a través de la misma, con desprendimiento de los contaminantes a la espuma (2), y entonces es evacuada en forma purificada como pasta aceptada (S¿).
