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 un peso molecular Mw medido por GPC de 100,000 a 3.106 g/mol y preparado mediante polimerización por radicales libres de al menos un monómero aniónico (m). La invención también se refiere a la suspensión producida cuya viscosidad Brookfield es superior a 2,000 mPa.s o cuyo umbral de flujo es superior a 40 Pa.
