Patent
·
OSTI ID:6883649
A method is described for treating tar sands bitumen froth. The froth is centrifuged in a first zone to separate coarse mineral particles, after which the froth is then treated in a second centrifuge zone to separate fine mineral particles. At least part of the fine mineral particle underflow from the second centrifuge zone is treated in the first centrifuge zone to remove additional bitumen associated with the fine mineral particles, and at least part of the thus treated fine mineral particles are removed from the first centrifuge zone along with the coarse mineral particles.
