Abstract: Systems and methods for extracting recoverable materials from source materials are provided. According to one embodiment, a plasma furnace includes an open-faced tray, a pair of arc rods, Faraday coils and a smooth interior surface. The open-faced tray carries tar sands from one end of the plasma furnace to another. The arc rods are disposed above the open-faced tray and are operable to generate a plasma energy field for vaporizing bitumen contained within the tar sands. The Faraday coils are positioned underneath the open-faced tray to create a magnetic field proximate to the tar sands and cause the plasma energy field to penetrate and heat the tar sands to a temperature sufficient to release a bond between the bitumen and the tar sands by focusing and drawing the plasma energy field through the tar sands. Vaporized bitumen condenses on the smooth interior surface from which it is collected.
