Cymbalisty, L M.O.

An apparatus is described for the mechanical separation of hydrocarbon material, such as bitumen, from an aqueous slurry of tar sand. The separation vessel consists of a vertically mounted elongated shell, an open ended cylinder coaxially mounted within the shell at about its midpoint and spaced apart from The shell to form an annular shaped passage around the mixing zone, dispersing means, preferably a number of rotatable vertical blades adjacent to a number of fixed blades, and a feed means for passing a slurry of water and tar sand into the mixing zone. The dispersion mechanism by shearing action breaks up the tar sand mixture into a multiplicity of small bitumen particles which rise upward in the vessel to form a froth. (8 claims)
