Dead burnt refractory dolomite is produced in rotary kilns. Generally high-grade dolomite, containing combined impurities less than 3%, is selected for dead burning. As it is difficult to densify high purity dolomite in a rotary kiln, it is customary to use some mineralizers to facilitate dead burning. Iron oxide is a common additive.

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.

Under-burnt lime generates less mortar and the quality is poor, which lowers the utilization of lime; if the calcination temperature is too high, the dark-color over-burnt lime with high density will be generated which will affect the project quality. Quicklime is a kind of white or grey block substance whose major component is CaO.

Project At a Glance: Content Headlines on CD ROM. Dolomite is a double carbonate of calcium and magnesium (CaCO3, MgCO3). ... are air dried and burnt to temperature ranging between 1200 to 1560oC for about one day which gives stabilized dolomite bricks. Dead burnt refractory dolomite is produced in rotary kilns;

Burnt dolomite for bricks making, should contain 50-55% CaO, 35-29.0% MgO, not more than 5-6 % SiO2 and not more than 5-8% ( Fe2O3 + Al2O3). Dolomite with calcination losses exceeding 2%, is under-burnt and cannot be employed for making Converter bricks.

Abstract. Five different Indian dolomites are densified by the process of two-stage sintering at 1923 K (1650°C). Hydration of the dead burnt dolomite by all three test methods is found to be strongly influenced by the bulk density and grain size of the dolomite. In spite of wide variations in test conditions, equivalent disintegrating actions ...

When burned in a kiln to drive off gases, calcite and dolomite form burnt lime. Among the uses for burnt lime, in addition to steel making, are water and sewage treatment, acid waste neutralization, and road base stabilization. Crushed calcite and dolomite are used in concrete, road construction, building materials, and as a filler in asphalt.
