The invention relates to the use of homopolymers and/or water-soluble copolymers of acrylic acid with one or more acrylic, vinyl or allylic monomers as dispersing agents for aqueous suspensions of mineral particles issuing from a mechanical and/or thermal reconcentration step following upon a step of wet grinding without the use of a dispersant and at low concentration in terms of dry matter. n The invention also relates to the said aqueous suspensions and their uses in the fields of paper, paint, fillers for synthetic resins and rubbers, detergent and cleaning formulations, ceramics, drilling fluids, cements, plasters and other fields of application in civil engineering and the construction industry. |
