Abstract
The invention relates to a method for treating an aqueous suspension of solid particles, wherein at least one water-soluble polymer is added to the suspension, and wherein said polymer is obtained by polymerizing at least a non-ionic monomer, optionally at least one anionic and/or at least one cationic monomer, in the presence of a multifunctional free radical transfer agent. This method is particularly useful for the treatment of mineral tailings and especially for tailings resulting from oil sand extraction.
