OIL SANDS FLUID FINE TAILINGS DEWATERING USING ADDITIVES

A process of treating and dewatering tailings is provided comprising mixing the tailings with a sufficient amount of a flocculant, a coagulant, or both, to promote flocculation/aggregation of the fine solids in the tailings; mixing a sufficient amount of a hydrophobicity modifying agent with the thu...

Beschreibung
Zusammenfassung:	A process of treating and dewatering tailings is provided comprising mixing the tailings with a sufficient amount of a flocculant, a coagulant, or both, to promote flocculation/aggregation of the fine solids in the tailings; mixing a sufficient amount of a hydrophobicity modifying agent with the thus treated tailings to modify the hydrophobicity of the flocculated/aggregated fine solids; and subjecting the resulting mixture to liquid solids separation to yield a solids product for reclamation and a liquid product for recycling or disposal.
