Abstract
Des procédés sont présentés en vue du traitement de flux de résidus des sables bitumineux et comprennent : (i) la mise en contact dune boue aqueuse de minerai de sables bitumineux ou de résidus de minerai de sables bitumineux avec au moins un sel de carboxylate pour former un flux de résidus de minerai de sables bitumineux floculés et (ii) la séparation des solides floculés du flux de résidus. Plus particulièrement, le procédé peut être utilisé pour faciliter la réduction de lhydroxyde de sodium pendant la récupération de bitume du minerai de sables bitumineux et le traitement des flux de résidus du minerai de sables bitumineux.
