Abstract
Procédé de retrait du bitume résiduel présent dans les résidus de sables bitumineux. Linvention comprend les étapes suivantes : facultativement, diluer les résidus avec suffisamment deau pour obtenir un apport en résidus présentant une teneur en solides allant denviron 18 % en poids à environ 36 % en poids; ajouter un coagulant ou un floculant, ou les deux, à la charge de résidus pour former une charge centrifuge; centrifuger la charge centrifuge pour produire un gâteau et un centrifugat ayant une teneur en solides de moins denviron 3 % en poids; introduire le centrifugat dans un dispositif de flottaison pour que de la mousse de bitume et un centrifugat propre se forment; recycler le centrifugat propre sous forme deau de dilution ou évacuer le centrifugat propre vers un bassin de résidus; et traiter davantage la mousse de bitume provenant du dispositif de flottaison soit en la renvoyant à la charge dextraction primaire, soit en la traitant dans une usine nouvelle ou actuelle de traitement des mousses.
