Abstract [en]

The generation of slags in steelmaking processes amounts to approximately 10 to 15 percent of the mass of metal produced. Landfilling of slag is increasingly regarded as unacceptable as it is a waste of resources as well as having the potential of leaching out heavy metals. In addition land for disposal is becoming increasingly scarce. Steelmaking slags have in many aspects good physical properties making them suitable for high quality demands such as concrete, asphalt layers and waterway construction. However, the technical quality and environmental characteristics of the slags are not always adequate and can sometimes limit their use. Modification of the properties of the slag may therefore be necessary. The article discusses methods that can be used for treatment of steelmaking slags, as well as various applications where slags of this kind are suitable. The slag projects that have been carried out at MEFOS in the recent years will also be highlighted. These include: - Stabilization of steelmaking slags by metallurgical treatment - Reduction of steelmaking slags for metal recovery by the IPBM process using a DC-furnace with a hollow electrode.
