PDF The Significance of Iron and Steel Slag As By- Product

Steel slag is a hard, dense material somewhat similar to air-cooled iron slag. During the production of steel in BOF and/or EAF scrap metal, or metalized ore, or both, the carbon and silicon are removed as carbon dioxide, and the remaining oxidized elements are combined with added lime to form steel slag. The composition

Life Cycle Assessment of Internal Recycling Options of ...

The internal recycling process of steel slag can save much primary raw materials, e. g. iron ore, limestone, and raw coal. SIIIb only consumes 38% of limestone compared to SI, while SIIIa consumes limestone for 54% of SI. The internal recycling process of steel slag can reduce the environmental impacts and resource bur- dens of crude steel.
