Stable aqueous suspensions of chalk whiting are prepared by (a) forming an aqueous suspension of chalk whiting containing from 70 to 85% by weight of solids, the chalk whiting comprising not more than 1% by weight of particles having an equivalent spherical diameter larger than 53 microns, and (b) thoroughly agitating the suspension, in the presence of a dispersing agent which is a water-soluble salt having an organic polymeric anion, until at least 5 horsepower hours of energy per ton of dry chalk whiting has been dissipated in the suspension. The optimum concentration of dispersing agent is 0À05 to 0.50% by weight based on the weight of chalk whiting. The dispersing agent is preferably a salt of polyacrylic acid but polymethacrylic acid salts and the condensation product of a sulphonated naphthalene and formaldehyde are also mentioned.
