ABSTRACT OF THE DISCLOSURE: A rotatable furnace for refining non-ferrous metals, particularly copper, comprises means for charging liquid metal, and adjoining oxidizing chamber, which is provided with slag- removing means at the shell of the furnace, and a reducing chamber, which communicates through a siphon-like partition with the oxidizing chamber. To permit the oxidizing and reducing treatments to be carried out within a wide range of the degree of filling of the furnace and to ensure that the refining furnace has a substantial buffer capacity for differ- ences of the rates at which metal is charged and tapped, the metal-tapping means are provided on the shell of the furnace on the same side as the opening for removing slag but below said opening.
