Abstract

L'invention a pour objet la préparation d'une suspension stable et pompable d'un carbonate de calcium minéral. On élimine les particules abrasives d'une suspension aqueuse concentrée et défloculée de carbonate de calcium minéral par centrifugation de la suspension ayant une concentration de matières solides d'au moins 65 % en poids, dans des conditions telles qu'on réduise la quantité de particules dans la suspension ayant un diamètre sphérique équivalent supérieur à 10 microns.
