Abstract
An indirect plasma-arc processor for aluminum dross is disclosed. The process involves melting aluminum dross in the presence of a flux in a furnace equipped with one or more arc-forming electrodes, wherein the arc is formed with a gas, such as argon. Molten oxides are removed from time to time, and the volatiles are removed via off-gas ducts.
