ABSTRACT:
Earth and sand containing bitumen, tar, and/or oil is broken down to particle sizes that can be suspended in water as a carrier for the particles, so that the suspension can be pumped upwardly through an inclined duct or separator where the suspended particles are subjected to horizontal ultrasonic vibrations of between about 18 and 27 kiloHertz for a period between about 5 and 10 minutes. These vibrations completely separate the hydrocarbons from the earth and sand, and entrap gases in the heavier-than-water hydrocarbons so that all the hydrocarbons float to the top of the duct or ultrasonic separator to form a layer which can easily be withdrawn. The cleaned earth and solid particles settle behind a baffled and perforated partition along and above the lower side of the duct or unit, from which lower side these cleaned particles can be removed. The water carrier is withdrawn near the upper end of the separator below the hydrocarbon layer, and recirculated to the lower end of the separator for suspending more hydrocarbon-containing particles.
