The invention consists in the use of dispersing agents, in a process of manufacture of an aqueous dispersion of mineral matter, by: a) grinding with a small amount of dry extract (.ltoreq.40%) of the said mineral matter in water without a dispersing agent and/or grinding aid agent, b) concentration with a large amount of dry extract (.gtoreq.65%) by mechanical and/or thermal means,characterised in that: at least one dispersing agent is introduced between stage a) and stage b), and/or during stage b), and/or during and after stage b). in the form of a combination: of at least one homopolymer of acrylic acid, and of at least one fluorinated mineral compound.
