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.

One recent idea is that the ordered arrangement of calcium and magnesium atoms in the dolomite structure does not form during precipitation. Rather, calcium- magnesium carbonate precipitates in a disordered manner, and then order emerges from a slow maturation process on a geological timescale (6, 7).The surface of the initial …
