| 20080282844 | METHODS FOR RECOVERING METALS FROM AUTOMOBILE SCRAP AND ELECTRONIC WASTE - A method of recovering the metal from automobile scrap and electronic waste. It includes separating the automobile scrap and the electronic waste to provide some metal pieces, washing and/or shredding and/or selecting said metal pieces to provide some groups of metal pieces having the same metal element, making a full-elemental analysis, comparing the weight of different metal pieces having the same metal element and attaining different combinations of value, weighted averaging the combination of value to calculate the full-elemental weighted average according to the different combinations of value, comparing said different full-elemental weighted averaging to different composite material, and finding a optimal set or some optimal sets, further disposing metal pieces according to the optimal set, and manufacturing alloy. Present invention has a lot of advantages, such as reducing pollution and cost, and processing more waste. | 11-20-2008 |
| 20080289450 | Conveyor System, Composite System and Method For Coupling Metallurgical Methods - A conveying system comprising elements for conveying lumpy, particularly hot, conveying stock and a cover for shielding the conveying stock. Disclosed are measures for inerting the conveying stock. A combined system encompasses a reduction plant for reducing oxides in a continuous process and processing unit for producing liquid metal in a discontinuous process. The reduction product is deliverable from the reduction plant to the processing unit. A method for coupling a reduction method used for reducing oxides in a continuous process and a method used for producing liquid metal in a discontinuous process. A reduction product from the reduction method is fed to the liquid metal production method for processing. | 11-27-2008 |

| 20090114063 | Method For Reducing And/Or Refining A Metal-Containing Slag - The invention relates to a method for reducing and/or refining a metal-containing slag. The aim of the invention is to improve reduction of the slag. For this purpose, calcium carbide (CaC | 05-07-2009 |
| 20090308205 | DIRECT SMELTING PLANT WITH WASTE HEAT RECOVERY UNIT - A direct smelting plant for producing molten metal from metalliferous feed material in a direct smelting process is disclosed. The plant includes a process controller for adjusting the volumetric flow rate of fuel gas supplied to a burner unit of at least one of the unit operations of the plant so as to at least meet selected requirements of the plant to operate the direct smelting process. | 12-17-2009 |
| 20110308354 | MATERIAL SUPPLY APPARATUS AND PROCESS - A material supply apparatus and process for co-injecting heated solid metalliferous material and solid carbonaceous material via a solids injection lance into a direct smelting vessel are disclosed. | 12-22-2011 |
| 20120006158 | PRODUCING METAL AND CARBON DIOXIDE WITH HYDROGEN RECYCLE - Offgas containing carbon dioxide and carbon monoxide that is produced in the reduction of ores and other metal oxides in a reactor is treated to reduce its carbon dioxide content and is then contacted with metal oxide to reduce the oxidation state of the metal and oxidize carbon monoxide therein to carbon dioxide, following which the reduced metal is oxidized with steam to produce hydrogen that can be fed to the reactor. | 01-12-2012 |
| 20120067171 | DIRECT SMELTING PROCESS AND APPARATUS - A process and apparatus for direct smelting metalliferous material is disclosed. The invention concentrates injection of solid feed materials comprising metalliferous material and carbonaceous material into a direct smelting vessel during the course of the process into a relatively small region within a metal layer in a molten bath in the vessel in order to generate a substantial upward movement of molten material and gas from the metal layer into a region in the vessel that is above the molten bath. In particular, the invention injects the solid feed materials with sufficient momentum and/or velocity via an opposed pair of lances that are oriented within the vessel and arranged to form overlapping plumes of injected material in the molten bath. | 03-22-2012 |
