Abstract
The present invention relates to a method for the treatment of a suspension of solid particles in water using water-soluble (co)polymers made from the hydrated crystalline form of 2-acrylamido-2-methylpropane sulfonic acid or of at least one of the salts thereof. This method is particularly useful for treating residues resulting from the mining industry.
