Abstract The rheology of mineral suspensions is highly dependent on the relationship between the mineral surface properties and inter-particle interactions as described by Derjaguin, Landau, Verwey and Overbeek (DLVO) theory. In this paper, the rheological properties of mineral suspensions are used to study the differences in behaviour of anisotropic talc and isotropic zircon minerals as a function of pH and polymer dosage (carboxymethyl cellulose, CMC). It was found that the rheological tests when carried out in parallel with electrophoretic or point of zero charge measurements clearly reveal differences between the behaviour of the suspensions of isotropic and anisotropic minerals. These differences are further accentuated with the addition of CMC.
