Abstract: It is important regarding environmental consideration to reuse the waste generated in steel plants. LD slag is mainly composed of calcium, silicon, iron and phosphorus but also contains trace amounts of potential toxic elements, specifically Cr and V which can be released. Although if directly discharged LD slag has negative impact on environment but it can be utilized judiciously to impart benefit to the environment by different ways mentioned in the paper. Moreover LD slag can be used as the base material or by material for the civil purposes, fertilizers etc. reducing environmental impacts.
