Jun 28, 2017· Dolomite is an anhydrous carbonate mineral. It is a double carbonate of calcium and magnesium (CaCO3.MgCO3). It is one of the important raw materials used in production of iron and steel. Dolomite contains theoretically 54.35 % of CaCO3 and 45.65 % of MgCO3 or 30.41 % of CaO, 21.86 % of MgO, and 47.73 % of CO2.
Aug 28, 2019· Dolomite is also used for making building stones and chips & powder used in flooring tiles. How will the dolomite market fare in the future? Demand for the production of construction materials as well as from the steel industry in coking applications will drive the global dolomite market over the forecast period.
