Abstract
La invención se refiere a un método para preparar una suspensión mineral acuosa a partir de un residuo de mineral metálico acuoso en el cual se introduce un polímero (P) que tiene una masa molecular Mw medida por GPC que varía de 2,000 a 20,000 g/mol y se prepara mediante polimerización radical de al menos un monómero aniónico (M). La invención también se refiere a la suspensión producida, cuya viscosidad Brookfield es inferior a 1,800 mPa.s o cuyo límite elástico es inferior a 80 Pa.
