Abstract
La invención se refiere a un método para controlar la sedimentación de una suspensión mineral acuosa de un derivado de minería mediante la concentración gravimétrica de la suspensión acuosa en presencia de un agente floculante y un polímero (P) que tiene una masa molecular Mw medida por GPC de entre 2000 y 20000 g/mol y se prepara usando al menos una reacción de polimerización de radicales libres de al menos un monómero aniónico (M). La invención <br /> también se refiere a la suspensión resultante, que tiene una viscosidad Brookfield de menos de 1,800 mPa.s o un límite elástico de menos de 80 Pa.
