    Abstract: Metal oxide-containing waste material is dried and preheated before being fed into a reactor (3) where it is melted and oxidised to produce a slag and a metal bath. The slag is then subjected to a two stage redn. pressure as it flows into an iron bath reactor (4) and then an iron bath calcinator (10). In the reactor, scrap or CO/CO2 is fed in to reduce mainly non-ferrous metals which form a bath which is subjected to segregation melting technique. A raw bronze melt is removed from the bottom of the vessel and recycled to the first reactor. In the second redn. stage, CaCO3, CaO and C and optionally O2 is fed into the vessel to reduce the FeO in the slag ad produce a pig iron melt.

    Abstract: PCT No. PCT/AT96/00019 Sec. 371 Date Sep. 24, 1996 Sec. 102(e) Date Sep. 24, 1996 PCT Filed Feb. 7, 1996 PCT Pub. No. WO96/24696 PCT Pub. Date Aug. 15, 1996To produce pig iron or steel and cement clinker from slags it has been proposed to react iron-oxide containing liquid slags, such as, e.g., steelworks slag, with iron oxide carriers, such as, e.g., ores, cinders or the like and lime to a ferrite-containing slag and to reduce the formed ferrite slag in a reduction reactor, such as, e.g., an iron bath reactor, whereupon the sinter phase is discharged as a clinker.

    Abstract: In a process for dechroming, and/or depleting the MgO content of, steel slags, oxygen is introduced into the liquid steel slag to an extent sufficient for converting iron quantitatively to iron oxide and at least 5% by weight of the iron oxide contained in the slag to iron-III-oxide. The oxidized slag obtained solidifies and is disintegrated, whereupon the paramagnetic portions formed are magnetically isolated and separated from the dechromed slag.
