摘要： A method of treating tailings comprising a solids fraction and a hydrocarbon fraction is disclosed. A primary flow is supplied to a jet pump, the primary flow comprising water and less than 20% solids by mass. A secondary flow is supplied to a mixing chamber of the jet pump, the secondary flow comprising a slurry of water and tailings, the slurry comprising more solids by mass than the primary flow. The jet pump is operated using the primary flow such that the tailings are agitated to effect at least a partial phase separation of the hydrocarbon fraction from the tailings. The methods disclosed herein may also be applied to treat tailings ponds.
