ABSTRACT:
A method and apparatus for thermally treating shale rock which holds an amount of hydrocarbon. The shale, preferably in a reduced size and form, is contacted by a hot molten metal bath at a sufficiently high temperature to release the hydrocarbon segment. The latter rises to the bath surface in liquid form to be skimmed, drained, or otherwise separated from residual rock material which is further conveyed from the lead bath.
