ABSTRACT:
A tool for slurrying and recovering minerals, including bitumen, from a single bore hole by hydraulic mining and jet pumping to the surface in which the tool includes conduits for pumping water into a venturi throat, a generally concentric bottom inlet to the venturi throat and a collection device below the venturi for lifting mineral into the venturi. The tool additionally includes means for selectively adjusting the distance between the screw and venturi throat to vary the proportion of suction applied to the bottom and side inlets to the venturi thereby accommodating variations in slurry concentrations and density.
