 · The second major use of dolomite is in steelmaking. In steelmaking dolomite is used both as a fluxing material and also as a refractory material. For use in steelmaking, the SiO2 (because of its acidic nature) content in the dolomite is to be very low preferably less than 1 %. When it is used as a fluxing material, it is used in calcined form.
