Sedimentation and filtration studies were carried out on the iron chloride solution containing 50 g/1 of TiO2 (rutile) particles. The work carried out on the laboratory scale indicated that both cationic and anionic flocculants could be effectively used to agglomerate fine rutile particles and thereby enhancing the sedimentation rate. The vacuum filtration data on thickened slurry showed improvement when flocculant was used. The filtraion mechanism followed intermediate blocking law model and cake filtration model for as such and flocculated slurry respectively.
