composition of trace elements in blast furnace slag

Chemical characteristics of iron and steel slag :

2011-9-8  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).In the case of steelmaking slag, the slag contains metal elements (such as iron) in oxide form
