Abstract (en)
[origin: EP2455429A1] Preparing an aqueous suspension of mineral material comprises: (a) providing at least one mineral material; (b) preparing an aqueous suspension comprising at least the mineral material; (c) grinding the mineral material of the aqueous suspension; and (d) optionally selecting and/or concentrating the aqueous suspension before dispersing the obtained concentrate. Preparing an aqueous suspension of mineral material comprises: (a) providing at least one mineral material; (b) preparing an aqueous suspension comprising at least the mineral material; (c) grinding the mineral material of the aqueous suspension; and (d) optionally selecting and/or concentrating the aqueous suspension before dispersing the obtained concentrate, where at least one amine and a vinyl-carboxylic acid polymer totally neutralized by a neutralizing agent different from the amine, is added between the steps (a), (b) and/or (c) or during step (c) or after step (c) during or after dispersing the obtained concentrate.
