Geochemical Characterization of Iron and Steel Slag and
As for the modern iron C-fine slag (AMFeC) its major element chemistry was similar to several modern steel slags and had one of the highest PRC (18 mg P/g of slag). For the experiments approximately 760 (ILSS5) and 790 (AMFeC) continuous pore volumes of 115 mg P/L synthetic influent solution with a HRTv of 8 h were reacted with the slag

Limestone and Dolomite and their Use in Iron and Steel
· Both limestone and dolomite are extensively used in an iron and steel plant in various processes. Specification of limestone and dolomite for iron making is less rigid. But for steelmaking limestone need to have very low SiO2 and Al2O3 since these elements require additional flux to neutralize them which increases the slag volumes.

Other compounds found in this material depend on the type of smelting. Non-ferrous smelting used to refine copper lead and similar metals produces highly ferrous slag as iron is an undesired element. Ferrous smelting such as that used to produce steel creates non ferrous slag as all the iron is used in the smelting process.

The role and selection of flux during high carbon
· CaO-al2o3-sio2 slag is commonly used in iron and steel smelting and the ash content of iron ore and coke is mostly acid oxides (SiO2 etc.) so alkaline fluxes (limestone or dolomite etc.) are mainly used. In some cases acidic fluxes (quartz or lean ore containing acid gangue) are also used to smelt iron ore containing alkaline gangue.

· 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 however because the refining time is short and the amount of limestone
