Abstract: A method and apparatus for melting aluminum uses a dense metal salt of Rubidium, Cesium, or Strontium. The salt is melted by a stinger and then superheated by AC applied to electrodes immersed in the salt. Aluminum in contact with the salt melts and floats on the salt. In continuous scrap melting, inflows and outflows of aluminum are comparable and may be shielded by inert gas. The superheated salt may be purified and may be heated in a separate reservoir and pumped to and from another reservoir containing salt and/or metal. The salt may be used to supplement the heating of an existing furnace.
