Abstract

L'invention concerne une méthode de contrôle de la sédimentation d'une suspension minérale aqueuse d'un dérivé minier par concentration par gravimétrie de la suspension aqueuse en présence d'un agent de floculation et d'un polymère (P) de masse moléculaire Mw mesurée par GPC allant de 2000 à 20000 g/mol et préparé par au moins une réaction de polymérisation radicalaire d'au moins un monomère anionique (M). L'invention concerne également la suspension produite dont la viscosité Brookfield est inférieure à 1 800 mPa.s ou dont le seuil d'écoulement est inférieur à 80 Pa.
