    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: In a method for desiliconizing pig iron prior to subsequent refining to steel molten steel slag after blast furnace tapping is charged onto the tapped pig iron bath, and optionally onto the blast furnace slag bath, in an amount corresponding to the Si content of the pig iron and the Fe and/or Cr oxide contents of the slag. The amount of steel slag is calculated such that the Si content of the pig iron is reduced to below 0.5% by weight at a simultaneous increase in the SiO2 content of the slag while reducing to liquid metals the Fe and/or Cr oxides of the slag. The slag-iron bath temperature is maintained at below 1500° C.

    Abstract: PCT No. PCT/AT96/00248 Sec. 371 Date Aug. 5, 1997 Sec. 102(e) Date Aug. 5, 1997 PCT Filed Dec. 6, 1996 PCT Pub. No. WO97/21843 PCT Pub. 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.
