Reuse of waste in integrated steel plants is important with regard to environmental and economic consideration. Slag generated from basic oxygen converter (LD-slag) is one of the recyclable wastes in integrated steel plants. This paper deals with the present use and possible use of LD-slag. The suitability of its use in roadmaking. meta-llurgical purposes and fertilizer production has been discussed. It is suitable to be used in roadmaking due to its high hardness and cementing property, Due to its high metallic value (Fe0-18%) and lime content (Ca0-45%), it is possible to use in BFironmaking and steelmaking to replace lime and recover iron. High phosphorous content (1-3%) restricts its use in ironmaking and steelmaking. Though, a little quantity of it is used in sinter making. the dephosphorisation is essential to improve its utilisation. The paper gives an overview of different approaches taken worldwide by several investigators for dephosphorisation of LD slag which makes it possible to be reused in iron and steel making. The authors draw a clear picture of worldwide research on LDslag recycling with some sugg-estions.
