| description | The present invention relates to a method for transporting, flocculating, and dewatering an aqueous tailings stream. Said method comprises adding a flocculant composition comprising a poly(ethylene oxide) (co)polymer with the aqueous tailings stream wherein the aqueous tailings stream has 15 wt% or less solids. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.
La présente invention concerne un procédé de transport, de floculation et de déshydratation d'un courant de produits de queue aqueux. Ledit procédé comporte l'ajout d'une composition de floculant comprenant un (co) polymère poly(éthylène oxyde) avec le courant de produits de queue aqueux, le courant de produits de queue aqueux contenant 15 % en poids ou moins de solides. Ledit procédé est particulièrement utile pour le traitement de suspensions de matière particulaire, notamment des boues minérales résiduaires, notamment pour le traitement de produits de queue et d'autres matériaux résiduaires résultant d'un traitement minéral, plus précisément, d'un traitement de produits de queue de sables bitumineux. |
