The effect of slurry density on a bitumen separation process based on a new cavitating jet technology at low temperatures is investigated. The experiments were conducted in a custom-made apparatus. It is shown that the cavitation effect does take place at increased slurry densities, and thus its application in industry will lead to increased efficiency of bitumen extraction. A comparison of the results for cavitating and noncavitating jets is provided to validate the effect of cavitation.
