ABSTRACT:
Apparatus for releasing bitumen components of an earth aggregate by establishing a current flow within an electrolyte contained in a volume of the aggregate which has been isolated from the surrounding earth. The current flow electrochemically acts on the molecular bonds between the bitumen and the aggregate, thus releasing the bitumen. In addition, gases are released and absorbed by the bitumen which, along with the heat produced by passage of the current through the electrolyte, acts to reduce the viscosity of the bitumen. As the viscosity is reduced to the stage where the bitumen is liquid, gravitational action allows the bitumen to separate from the aggregate into a stratum which permits easy removal thereof.
