CONSTITUTION:The high temp. melting chamber 3 is arranged with an adjacent combustion chamber 4 partitioned with a heat conducting partition wall 2 and heated to a high temp. of 1200 deg.C with a gas burner 26 arranged in the melting furnace 1 for waste material, such as the cut layer of Al. The high temp. gas with the burner 20 is supplied into a heat resistant cylinder 29 from an outlet 5 through a retention chamber 6 while continuously carrying in the right direction 36 with a screw blade 30 arranged on the outer periphery of the heat resistant cylinder 29, and the Al layer 18 is supplied into the heat resistant cylinder 29 rotating round a shaft 34 from a charging hole 19. The foreign matter in the Al layer 18 is burnt and removed by compressing while preheating the Al layer. The Al layer from which the foreign matter is removed is supplied into the high temp. melting chamber 3 under pressurizing with the screw blade 10, and after melting at the high temp. without oxidizing, the Al layer 18 is pressurized with a pressurizing blade 11 and discharged into a retention chamber 16 from a bottom part discharging hole 13 of the high temp. melting chamber 3. Then, the Al layer 18 is overflowed in the arrow mark 41 direction and supplied into a molten metal storing furnace from a discharging passage 17 in the high yield.

摘要： PURPOSE:To stabilize aluminum dross, to facilitate handling and storing of the aluminum dross and to effectively utilize the aluminum dross by adding a specific amt. of water to the aluminum dross and mixing and stirring both, then holding the mixture and evaporating the added water by the heat of hydrolysis. CONSTITUTION:The water is added at 5 to 50wt.% to the aluminum dross in the form of fine powder recovered in primary and secondary refining process of aluminum and both are mixed and stirred by a mixer. The aluminum dross is thereafter held in a vessel where the added water is evaporated by the generation of heat according to the hydrolysis. Combustible gases contg. the harmful gases generated in part thereof at this time are preferably captured and burned. The stabilized aluminum hydroxide is formed by the hydrolysis. Particles of unreacted metal aluminum, aluminum nitride, magnesium silicate, etc., are stabilized as dense protective films.

摘要： PURPOSE:To utilize a difference in stability to the temp. of gaseous phase metals so as to separate the metals by halogenating the combustion residues of fossil fuel, then forming gaseous phase metal complexes by a specific complexing agent and introducing these complexes into cracking zones having a temp. gradient. CONSTITUTION:A vessel 7 contg. AlCl3 which is the complexing agent is arranged at the front end of a quartz reaction tube 1 and a vessel 9 housing the fuel residues of the fossil fuel is arranged in the part succeeding thereto to provide the reaction tube with regions A-1 to A-13 having a temp. gradient. The gaseous mixture composed of N2CCl2 is introduced into the reaction tube from its left end while the reaction tube 1 is kept heated by an electric furnace 35. The AlCl3 is heated to evaporate and the metal components, such as V, in the combustion residues in the vessel 9 are chlorinated. The formed metal chloride reacts with the evaporated AlCl3 and form the respective gaseous phase metal complexes. The gaseous phase metal complexes move together with N2 of a carrier gas to a low pressure side in the reaction phase 1 and are made into metal chlorides in the regions of the cracking temp. of the respective metal complexes. These metal chlorides are separated and precipitated into A-1 to A-13. The valuable metals in the combustion residues are thus effectively separated and recovered.

摘要： PURPOSE:To control the discharge of cold ash additionally charged and to enhance recovering yield of a metal by arranging an infrared thermo-sensor for detecting the surface temp. of remaining slag to be treated in a crucible above the crucible while avoiding an ascending/descending course of a stirring blade inserting/leaving to/from the crucible. CONSTITUTION:The metal-remaining slag for recovering the metal content is charged into the crucible 2 and an exothermic agent is added to execute the exothermic reaction and the stirring blade 5 is desceneded into the crucible 2 to stir the remaining slag to be treated, and the oxide and the molten metal are separated under a high temp. At this time, the infrared thermo-sensor 8 for detecting the surface temp. of the remaining slag to be treated in the crucible is arranged in a machine frame 1 above the crucible while avoiding the ascending/descending course of the stirring blade 5 inserting/leaving to/from the crucible 2. By this method, the discharge of the cold ash additionally charged into the crucible 2 is controlled. When the surface temp. of the remaining slag exceeds a prescribed temp., the preset quantity of the cold ash is discharged and charged into the crucible and the ascending/descending movement of the stirring blade 5 is controlled with a timer to enhance the metal recovering yield.
