METAL MELTING FURNACE ABSTRACT OF THE DISCLOSURE A refractory lined melting furnace particularly suited for separation of non-ferrous metals with embedded or attached ferrous components, includes a casing or body pivotally mounted and tiltable by means of fluid opera- tors. The interior is divided by two vertical walls into a combustible waste burning portion for the generation of combustible gases to assist in heating the furnace, and a melt chamber into which a variety of metallic waste can be charged for melting. A conventional fire burner is sup- plied to the melt chamber. The temperature of the melt chamber is raised to the melting point of the metallic waste material having the lowest melting point, e.g. alu- minum, and when the aluminum is melted, the aluminum runs through drainage apertures into a liquid metal holding chamber provided on the floor of the melt chamber. When the molten metal has drained, the furnace is tilted rear- wardly to discharge the remaining scrap out through rake- out doors at the rear of the melt chamber. The sequence is repeated with heat being supplied from the combustible gases formed in the combustible waste burning portion, un- til the storage chamber is full whereupon the furnace is tilted and the molten metal discharged from a tapping hole in the front of the storage chamber.
