  • Dolomite Cargo Handbook the world's largest cargo

    Dolomite is chiefly used as refractory, ramming, and fettling material in steel melting shop, and as fluxing material in blast furnace operation in secondary steel and ferromanganese manufacture. To a lesser extent it is used in the glass industry especially in sheet-glass manufacture. It also finds use in the manufacture of mineral wool.

    10/15/2014· Both reactive MgO and CaO are alternative activators for ground granulated blast furnace slag (GGBS). In this study natural dolomite, as a source of MgO and CaO, was calcined at 800 °C (D800) and 1000 °C (D1000) in air. The activation of GGBS with the calcined dolomites was investigated using compressive tests, pH measurement of pore solutions, powder X-ray diffraction (XRD) and

    The type of dolomite used in blast furance, sinter, and pellet plants is of same quality but it is of inferior grade as compared to that used in steel melting shop. The ISI stipulates that dolomite for use in BF /SP should contain MgO 18% (min), CaO 28% (min) and acid insolubles 8% (max), whereas steel plants in practice, consume dolomite with MgO 18 to 19.5%, CaO 29 to 30% and acid insolubles 6 to 10%.
