Date Nov. 7, 1996In a process for the production of hydraulic binders, crude steel and/or alloys, such as, e.g., FeCr or FeV, from basic steel slags containing chromium and/or vanadium, the liquid steel slag is mixed with an additive selected from the group consisting of blast furnace slag, electric arc furnace slag, dusts from steel production, metallic waste substances or refuse incineration residues and/or with acid additives for lowering the viscosity, whereupon steel is sedimented out of the liquid slag and the remaining slag in a first reduction stage is reduced to metallic iron having an iron oxide content of below 5 wt. % and above 1 wt. %, whereupon the remaining slag melt in a second reduction stage having a higher reduction potential as compared to the first reduction stage is further reduced to metallic Cr or V or ferroalloys thereof and the hydraulically active slag is separated.

Date Jun. 19, 1997The method for processing waste or waste fractions, such as, for example, household refuse, car shredder light fractions or the like, provides for pyrolysis, gasification and/or combustion, whereupon the residues are melted under reducing conditions. The reduced portions are then are subjected to a stepwise oxidation, with chromium being quantitatively separated in a first oxidation stage. After this, a calcium ferrite slag is formed by further oxidation, whereupon the remaining metal bath is further processed in order to recover nonferrous heavy metals.

Abstract: Waste (such as domestic garbage, industrial waste, and bulky refuse) or sewage sludge is pretreated by pyrolysis under an oxygen-poor atmosphere to provide solid pyrolysis residues and a pyrolysis gas. The solid pyrolysis residues are mechanically treated to provide a coarse fraction and a fine fraction. The coarse fraction is mechanically separated and fed to a metal bath reactor containing a metal bath and a liquid slag floating on the metal bath. The fine fraction entrained in a carrier gas is fed via a nozzle in order to carburize the metal bath. The carburized metal bath functions to reduce metal oxides from the liquid slag floated thereon, thereby purifying the liquid slag. At least a portion of the pyrolysis gas is used to smelt and heat the liquid slag.

Abstract: PCT No. PCT/AT97/00256 Sec. 371 Date Jul. 29, 1998 Sec. 102(e) Date Jul. 29, 1998 PCT Filed Nov. 21, 1997 PCT Pub. No. WO98/23550 PCT Pub. Date Jun. 4, 1998The cement composition of this invention includes 10 to 35% by weight of portland cement, 65 to 90% by weight of a synthetic pozzolan, and an activator for reducing the positive surface potential of the synthetic pozzolan. The synthetic pozzolan is obtained by an at least partial reduction from combustion residues having a SiO2/CaO ratio of greater than 1:1 and containing Na2O and K2O as alkali oxides in an amount exceeding 1.5% by weight. The activator includes anionically active or anionic tensides.

Date Jan. 12, 1995The reactor (1) that is used to melt combustion residues incorporates a vertical partition wall (4) that incorporates return flow openings (7) and an overflow (6), wherein foamed slag is produced in the chamber (3) by the injection of gases through base nozzles (10) and the foam collapses in the second chamber (5) or the return flow channel. The liquid slag is drawn off through the taphole (11) after the desired conversion.

Abstract: The invention concerns a method of producing pig iron, non-ferrous metal alloys, ferrochromium carbides or carbon-free ferrochromium and synthetic blast furnace slag using residues of incinerated waste or slag containing metal oxides. According to the invention the materials used in waste-incineration, such as for example light fractions obtained from vehicle shredders and blast furnace dusts, are (1) oxidised at least partially and then reduced, with the deposition of non-ferrous metals or alloys. The oxidic slag phase, depleted of metals or alloys, is then (3) mixed with liquid steelworks slag, optionally with the further addition of blast furnace dusts, whereupon, as the viscosity of the steelworks slag is reduced, raw steel is extracted, and (4) the remaining slag portion is subjected to further reduction, producing pig iron and possibly ferrochromium alloys. The resultant synthetic blast furnace slag is then discharged.

Abstract: The process for processing waste or fractions thereof, e.g. domestic rubbish, light car shredder fractions or the like, comprises pyrolysis, gasification and/or burning in which the residues are melted in reducing conditions. The reduced metal components are subsequently subjected to stepwise oxidation, where chromium may be quantitatively separated in a first oxidation step. Subsequent oxidation forms a calcium-ferrite slag, whereupon the remaining metal bath is further processed to obtain non-ferrous heavy metals.
