An apparatus and method are described for 1) reducing agglomerated masses of tar sand, and 2) recovering as a bituminous product the bituminous matrix material. The apparatus includes a vessel which is divided into an attrition zone enclosed by a screen member, a sand separation zone, and a product recovery zone. The vessel accommodates liquid which is a solvent into which the agglomerated masses of tar sands are introduced. The liquid is impelled vigorously upward into the attrition zone to create a high shear environment by which the tar sand masses are reduced into sand particles coated with the bituminous matrix material of the tar sand. The separated grains of sand also are stripped of the bituminous product by the high shear environment. The cleansed sand passes through the screen member surrounding the attrition zone into the sand separation zone. The liquid and the bituminous product removed from the sand pass to the product recovery zone. 8 claims.
