Oil sands ore containing bitumen is treated in a reactor chamber by ultrasonic oscillations impact such that cavitation of ore molecules occurs. The disintegration of the pulsating bubbles in the cavitation results in the separation of the oil, water, sand and air fractions of the oil sands. The oil fraction may be continuously extracted for subsequent …
