A method for separating the alkaline ore and spent carbon fractions contained in spent electrolytic cell cathode comprising the steps of: (a) grinding the spent cathode to a suitable particle size; (b) treating the product of step (a) with ultrasonic energy, sulfuric acid, or both, for a period sufficient to achieve a measurable particle size distinction between the alkaline ore and carbon particles; and (c) screening the alkaline ore and carbon particles to achieve separation of the alkaline ore particles which pass through the screen from the carbon particles which are retained on the screen.
