Abstract: An apparatus (10) and method for recovering elemental carbon, elemental sulfur, elemental iron, elemental gold and other elemental materials from an air flow including a funnel-shaped receptor (14) and an inverted cone-shape electrode node body (12) spaced from the funnel receptor, a funnel-shaped reaction zone (45) between the outer surface of the electrode node body and the inner surface (60) of the receptor for receiving the air flow, and a plurality of point source electrodes (36) mounted to the electrode node body (12) and projecting into the reaction zone (45). The electrode node body (12) and the receptor (14) are electrically isolated from each other, the receptor (14) is connected to ground, and a voltage source is electrically connected to the electrode node body (12).
