    摘要： A process and an apparatus are disclosed for improved recovery of metal from hot and cold dross, wherein a dross-treating furnace is provided with a filling material with good capacity to store heat. This filling material is preheated to a desired temperature by injection of an oxidizing gas to burn non-recoverable metal remaining in the filling material after tapping of the recoverable metal contained in the dross and discharging of the treatment residue. When dross is treated in such furnace, the heat emanating by conduction from the filling material is sufficient to melt and separate the recoverable metal contained in the dross, without addition of an external heat source, such as fuel or gas burners, plasma torches or electric arcs and without use of any salt fluxes. Furthermore, the recovered metal being in the molten state can be fed to the molten metal holding furnace without cooling the melt; in addition, the non-use of fluxing salt for the treatment means that the non-contaminated residue can be used as a cover for the electrolytic cells in the case of aluminum. In the case of zinc dross, the residue is a valuable zinc oxide by-product very low in contaminants.

    摘要： A method and apparatus for harvesting waste thermal energy from a pyrometallurgical vessel (1) and converting that energy to direct electrical current, the method including deriving and controlling a primary fluid flow (103) from a primary heat exchanger (10) associated with the pyrometallurgical vessel (1), providing a secondary heat exchanger (12) physically displaced from the pyrometallurgical vessel (1) which exchanges heat between the primary fluid flow (103) from the primary heat exchanger (10) and a secondary fluid flow (104). The secondary heat exchanger (12) has at least one thermoelectric or magneto-thermoelectric device having two operationally-opposed sides, the operationally-opposed sides being in thermal communication with the primary and secondary fluid flows (103,104) respectively. A temperature difference is maintained between the two operationally-opposed sides of the thermoelectric or magneto-thermoelectric device and electrical energy is generated from the temperature differential. The pyrometallurgical vessel preferably generates a magnetic field (14) in the region surrounding the pyrometallurgical vessel (1) and the secondary heat exchanger (12) having at least one magneto-thermoelectric device is positioned physically displaced from but within the magnetic field (14) surrounding the pyrometallurgical vessel such that the direction of temperature gradient across the secondary heat exchanger is oriented normally to the maximum principal direction of the magnetic field (14) and electrical energy is generated from the temperature differential and magnetic field via the Nernst effect or magneto-thermoelectric effects.
