ABSTRACT:
A portable highly versatile thermal metal refining apparatus for selectively reclaiming metals from a mixed or combined load of materials having varied melting temperatures. A refining chamber cylindrically shaped about a central axis having oppositely disposed open and closed ends defines an internal reduction cavity loaded through its open end. The chamber cavity is lined with durable glass, enabling successive reduction cycles of different metals without carry-over contamination. Detachable support and drive means mount the refining chamber for operative rotation about the central axis, and pivotal means are provided for controlling the operative pitch of the central axis. Field supply means, operable from available field sources, provide a controlled fuel/air mixture to a burner nozzle at the closed end of the chamber for directing a reducing flame toward a load within the reduction cavity. A freestanding reflector panel minimizes heat loses from the open end of the chamber while maintaining loading access therethrough.
