Abstract (en)
[origin: WO2019234315A2] The invention relates to a method for controlling the sedimentation of an aqueous mineral suspension of a mining derivative by means of the gravimetric concentration of the aqueous suspension in the presence of a flocculating agent and a polymer (P) which has a GPC-measured molecular mass Mw of between 2000 and 20000 g/mol and is prepared using at least one free radical polymerisation reaction of at least one anionic monomer (M). The invention also relates to the resulting suspension, which has a Brookfield viscosity of less than 1 800 mPa.s or a yield point of less than 80 Pa.
