Abstract
This invention relates to a method and apparatus for beneficiating relatively small shredded scrap metal particles, such as aluminum metal particles preparatory to remelting the same, by passing the particles through a beneficiating chamber that is heated to a substantially uniform elevated metal temperature throughout and while passing the particles through such chamber effecting a vaporization of the non-aluminum volatiles, such as coatings, paints and lacquers that adhere to said particles and while avoiding ignition of the said volatiles.
