Abstract
Un proceso en el que el material que comprende un liquido acuoso con solidos de particulas dispersas se bombea como un fluido y luego se deja reposar y hacer rigido y se mejora el rigidizado mientras que retiene la capacidad de bombeo del material al combinar particulas polimericas con el material durante o antes de bombeo del material, en donde las particulas polimericas comprenden polimero soluble en agua que tiene una viscosidad intrinseca de al menos 3 dl/g. El proceso de la invencion minimiza en forma mas efectiva el area ocupada por una pila del material de un volumen determinado mientras que se mantiene la capacidad de bombeo del material. Esta invencion es particularmente adecuada para material que comprende lodo rojo del proceso de alumina Bayer.
