Abstract
A method for separating a substance such as a hydrocarbon from a particulate material such as soil is provided. An aqueous slurry is formed and a shear force is applied to the slurry, such as in a reversible helical screw conveyor, while the slurry is vibrated. The substance thus separated can then be removed from the particulate material.
