Title (EN) METHOD AND COMPOSITION FOR TREATING TAILINGS
(FR) PROCÉDÉ ET COMPOSITION DE TRAITEMENT DES RÉSIDUS
Abstract:
(EN) The invention relates to method and composition for treating tailings from a separation process, where bitumen is separated from mineral solids. Tailings comprise an aqueous phase with suspended solid particulate material and residual bitumen and have a dry solids content < 25 weight-%. The method comprises addition of a flocculating agent comprising polyacrylamide to the tailings, as well as addition of an auxiliary agent comprising ionic liquid to tailings in conjunction with the flocculating agent. Flocs, which comprise solid particulate material, are formed and the formed flocs are separated from the aqueous phase. The composition comprises a copolymer of (meth)acrylamide and an auxiliary agent comprising ionic liquid.
(FR) L'invention concerne un procédé et une composition de traitement des résidus d'un processus de séparation, le bitume étant séparé des solides minéraux. Les résidus comprennent une phase aqueuse avec un matériau particulaire solide en suspension et du bitume résiduel et ont une teneur en solides secs < à 25 % en poids. Le procédé comprend l'ajout d'un agent floculant comprenant du polyacrylamide aux résidus, ainsi que l'ajout d'un agent auxiliaire comprenant un liquide ionique aux résidus conjointement à l'agent floculant. Des flocons, qui comprennent un matériau particulaire solide, sont formés et les flocons formés sont séparés de la phase aqueuse. La composition comprend un copolymère de (méth)acrylamide et un agent auxiliaire comprenant un liquide ionique.
