Title (EN) TERPOLYMERS FOR OIL SANDS TAILINGS TREATMENT
(FR) TERPOLYMÈRES POUR LE TRAITEMENT DE RÉSIDUS DE SABLES BITUMINEUX
Abstract:
(EN) Terpolymers and use thereof are provided comprising one or more nonionic monomers, one or more anionic monomers and one or more cationic monomers, These terpolymers and compositions containing may be used as flocculants, for example, for treating tailings, such as oil sands tailings, to facilitate solid-liquid separation, for example, in order to efficiently recycle water and/or to reduce the volume of tailings which may be transferred to a tailings pond and/or to a dedicated disposal area.
(FR) L'invention concerne des terpolymères et leur utilisation, lesdits terpolymères comprenant un ou plusieurs monomères non ioniques, un ou plusieurs monomères anioniques et un ou plusieurs monomères cationiques. Ces terpolymères et les compositions contenant ceux-ci peuvent être utilisés en tant que floculants, par exemple, pour traiter des résidus tels que des résidus de sables bitumineux, pour faciliter la séparation de matières solides-liquides, par exemple, afin de recycler efficacement de l'eau et/ou de réduire le volume des résidus pouvant être transférés vers un bassin de résidus et/ou vers une zone d'élimination spécifique.
