A method of treating alum shale and other bituminous shales in order to extract oil et cetera, is characterized by bringing the shale to a temperature at which it melts, and at which the necessary amount of heat is transferred to the molten shale to be distilled. The patent claim is characterized by heating the shale by means of electric current. The patent has one additional claim.
