Abstract

Un procédé dans lequel un matériau comprenant un liquide aqueux renfermant des solides particulaires dispersés est transféré comme fluide dans une zone de dépôt, puis laissé au repos et rigidifié, et dans lequel la rigidification est améliorée et la fluidité du matériau maintenue pendant le transfert, en combinant au matériau une quantité rigidifiante efficace d'une solution aqueuse d'un polymère hydrosoluble. Le procédé convient particulièrement au traitement des sous-écoulements de résidus provenant de l'opération de traitement des sables bitumineux et le co-dépôt de fractions fines et brutes de résidus. De plus, la liqueur libérée pendant l'étape de rigidification est de grande clarté.
