7984866 Relocatable oil sand slurry preparation system July 26, 2011
A relocatable oil sand slurry preparation system is provided for preparing an aqueous oil sand slurry amenable to pipeline conveyance while producing minimum overall rejects, comprising (a) a relocatable rotary digester for slurrying oil sand and water and digesting oil sand lumps to
7763166 Relocatable countercurrent decantation system July 27, 2010
A process line for separating oil sand slurry comprising coarse solids, fines, bitumen and water, into a first product comprising bitumen, fines and water and a second product comprising coarse solids, fines and water is provided comprising a plurality of countercurrently operating s
5264118 Pipeline conditioning process for mined oil-sand November 23, 1993
As-mined, naturally water-wet oil sand is mixed at the mine site with hot water and NaOH to produce a slurry containing entrained air. The slurry is pumped through a pipeline and is fed directly to a conventional gravity separation vessel. The pipeline is of sufficient length so that, in
5039227 Mixer circuit for oil sand August 13, 1991
The mixer circuit comprises a vertically oriented, open-topped mixer vessel having a cylindrical side wall terminating with a shallow conical bottom. The bottom wall forms a central bottom outlet. Recycled slurry and fresh water streams are fed tangentially to the inner surface of the ve
4545892 Treatment of primary tailings and middlings from the hot water extraction process for recovering October 8, 1985
The primary tailings and middlings are combined and fed to a vessel having the general form of a deep cone thickener. The feed is deflected outwardly and generally horizontally by a baffle, as it is delivered to the vessel. Simultaneously, the outwardly radiating layer of newly added fee
