The rheological behavior of aqueous hematite slurries has been studied by laboratory viscosity and flow measurements. Data are presented for slurries with volume concentrations of hematite up to 40%. Solids concentration and particle size distribution were found to be important variables in the rheological behavior of hematite slurries as contrasted to temperature which was found to have only a small effect. Chemical dispersant additives and viscosity control additives used in relatively small concentrations improved the flow characteristics of the hematite slurries. Specifically, a lignosulfonate dispersant markedly increased the flow of slurries containing finely divided hematite, −325 mesh, and a viscosity control additive increased the carrying capacity of other slurries for coarse particles.
