<p>For quenching dross skimmed from a molten aluminum surface, the dross is placed in a container in successive layers separated by layers of particulate salt. Heat is taken up from the dross not only in elevating the temperature of the salt, but also as heat of fusion of the salt. The salt used may comprise one or more components of a salt flux suitable for employment in subsequent procedures to recover free metal from the dross.</p> |
