Innovative New Function of Steelmaking Slag as Rehabilitation Material of Coastal Environment
Innovative new methods to further utilize steelmaking slag must be developed from the viewpoint of not only the stable consumption of steelmaking slag but also the establishment of sustainable and environmental-friendly steelmaking process.It is well known that the lack of iron ion in seawater,which is an essential minor nutrient for seaweeds and phytoplanktons,is one of major reasons of the severe deterioration of coastal environment all over the world.The trial application of steelmaking slag as a material to supply such mineral nutrients has revealed the positive effects on the improvement of ocean environment.Dissolution mechanisms of various materials from steelmaking slag into seawater must be clarified in detail in order to fully apply the technology to seriously damaged coasts.The dissolution behavior of various elements from steelmaking slag,or the mixture of steelmaking slag and various additives has been observed in the present study and the reaction mechanisms between various materials produced from steelmaking slag and seawater have been discussed.
