<p>TITLE: RECOVERING NON-VOLATILE METALS FROM DUST CONTAINING METAL OXIDES A method of recovering non-volatile metals from material in dust form containing metal oxides, comprising the steps of blowing the material into the lower portion of a reactor, said reactor containing a solid reducing agent, passing said starting material into a reduction zone within said lower portion, said reduction zone being maintained by the use of a plasma generator adjacent thereto, substantially instantaneously reducing and melting said starting material in said reduction zone, and removing the melted and reduced metal product from the bottom of the reactor.</p> |
