Abstract
A method for preparing an aqueous mineral suspension from an aqueous metal ore residue may include introducing into the aqueous metal ore residue a polymer (P) having a molecular mass Mw measured by GPC ranging from 2,000 to 20,000 g/mol. The polymer (P) may be prepared by radical polymerization of at least one anionic monomer (M). The suspension produced by such a method may have a Brookfield viscosity of which is lower than 1,800 mPa·s or a yield point of lower than 80 Pa.
