ABSTRACT:
A process for recovering free aluminum and aluminum compounds such as aluminum oxide from aluminum dross and aluminum scrap in a furnace heated with a plasma arc torch followed by oxygen injection after significant aluminum separation has occurred is described. The injected oxygen reacts with aluminum nitrides and unrecoverable aluminum in the dross to provide processing energy. High aluminum recovery is obtained with greatly reduced cycle times at lower overall operating costs.
