Pyrometallurgical recovery of copper from slag

In accordance with the present invention, copper is extracted pyrometallurgically from slag material containing dissolved and/or entrained copper values. The slag material, containing from about 1 to 10 percent by weight of copper, either dissolved or entrained therein, is melted in a rotary reactor and subjected to a two-stage cleaning process.
