Abstract
To 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.
