Abstract
La présente invention concerne une méthode de traitement d'une charge bitumineuse. La charge bitumineuse est mise en contact avec une liqueur d'extraction pour former une boue. Un liquide portant est ajouté à la boue à au moins deux stades, et les solides présents dans la boue sont agités pour former une boue agglomérée comprenant des solides agglomérés et un extrait de bitume à faible teneur en solides. Les agglomérats sont ensuite séparés de l'extrait de bitume à faible teneur en solides. Les avantages éventuels peuvent comprendre la production d'agglomérats plus fins et plus uniformes. Le premier aspect peut mener à une meilleure récupération du bitume tandis que le deuxième aspect peut améliorer le taux de séparation solide-liquide. Le liquide portant peut être ajouté dans une zone où les vitesses de cisaillement sont relativement élevées. Entre les stades d'ajout du liquide portant, les agglomérats peuvent être retirés.
