  • Metal recovery method
    Patent number: 3984090
    Abstract: A non-ferrous metal is recovered from a batch of scrap material by combustion of a fuel to generate heat and transmittal of said heat to the material by convection flow. The flow rate of fuel is regulated to obtain and maintain an optimum temperature below the melting point of the metal causing decomposition of non-metallics in the batch of scrap material within a non-oxidizing atmosphere.
