Abstract
The effect of humic acids on the agglomerate structures of kaolinite and montmorillonite
particles as well as their natural mixture in dilute H-clay suspension has been
studied. It has been observed that humic acids even when added in small proportion
in H-kaolinite suspension, the agglomeration of the particles disappear and they remain
in dispersed state. No such effect is observed either in montmorillonite or in mixture
of kaolinite and montmorillonite suspension where particles also exist in agglormerated
form. A possible mechanism has been suggested to explain their behaviour with humic
acids.
