A method of dewatering mineral-containing sludge comprising adding to the sludge (a) an aqueous solution or emulsion of acrylamide polymer flocculating agent and (b) a microfiber additive. By using this method, such mineral-containing sludges can be quickly dewatered into a cake comprising 25-35% solids which can then be further processed to a 60% solids-containing material. The method is particularly suitable for use in methods for treating, recovering, rehabilitating and recycling residue of mining operations. With modification, the method is also suitable for dewatering organic sludges.
Un procédé de déshydratation de boues renfermant des minéraux consiste à ajouter à celles-ci (a) une solution aqueuse ou une émulsion d'agent floculant polymère acrylamide et (b) un additif microfibreux. Grâce à ce procédé, des boues contenant des minéraux peuvent être rapidement déshydratées en un gâteau renfermant 25 à 35 % de solides, qui peut ensuite subir un traitement ultérieur pour donner une matière contenant 60 % de solides. Ce procédé convient notamment pour traiter, récupérer, réhabiliter et recycler des résidus d'exploitations minières. Moyennant modification, ce procédé convient également pour déshydrater des boues organiques.
