ABSTRACT:
An improved mechanism for recovery of metal, particularly aluminum, from metal bearing dross utilizes a trough for collection of the dross. A wedge member compresses the dross in the trough. In this manner, metal is decanted from the compressed dross and flows through slots in the bottom or passages in the walls of the trough for collection in a pan, or becomes concentrated at the edges or walls of dross. The trough and wedge members also serve to cool the dross material thereby diminishing metal loss due to thermite reaction.
