Abstract: A device and method for recovering metal accompanying slag skimmed from the surface of a bath of molten metal are described. The device has the form of a trough provided with a perforated bottom member, which is intended to be located at substantially the same level as the surface of the molten metal in the furnace. When using the device, slag is charged thereto and heated to a temperature which is at least equal to the temperature of the metal being treated. Whereupon any metal in the slag melts and runs down through the perforated bottom member of the device in the molten metal bath. Residual components of the slag are then removed from the device.
