Chemical characteristics of iron and steel slag : NIPPON,
Chemical composition of iron and steel slag The primary components of iron and steel slag are limestone (CaO) and silica (SiO 2 ). Other components of blast furnace slag include alumina (Alsub>2 O 3 ) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO).MSDS: Slag Material Safety Data Sheet,with large amounts of dry powder or with wet slag can cause moderate eye irritation. Eye exposures require immediate first aid to prevent significant damage to the eye. Skin Contact: Slag may cause dry skin, discomfort, irritation, and dermatitis.Steel slag in China: Treatment, recycling, and management,,Because of its chemical composition, including calcium oxide (CaO), Fe, iron oxide (FeO), silicon dioxide (SiO 2), magnesium oxide (MgO), and manganese oxide (MnO), steel slag can be reused as a raw material in steel plants (including the sinter and converter); (Topkaya et al., 2004, Diao et al., 2016, Sarfo et al., 2017a, Sarfo et al., 2017b).
