Abstract: A method of processing a heterogeneous material includes entraining heterogeneous particles into a fluid stream. Each of the heterogeneous particles comprises a liquid portion and a solid portion. The fluid stream is passed through at least one adjustable nozzle, and is impacted to dissociate the liquid from the solid. A method of separating oil from solid particles includes mixing oil-coated solid particles with water to form a slurry, passing a first portion of the slurry through a first nozzle, and passing a second portion of the slurry through a second nozzle such that the second portion of the slurry intersects the first portion of the slurry to separate the oil from the particles.
