Dolomite Calcination Range

Effect of natural dolomite calcination temperature on ...

May 01, 2013 · Natural dolomite was calcined at 700–900 °C under air and an Ar gas flow atmosphere to characterize its sorbency potential for borate. A sequential decarbonation occurred with increase in calcination temperature, that is, transformation of CaMg(CO3)2 to MgO and CaCO3 up to 700 °C and CaCO3 to CaO from 700 to 900 °C.

Jun 28, 2017 · 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. However, in nature, dolomite is not available in this exact proportion. Hence generally the rock containing in the range of 40 % to 45 …

Calcination Of Dolomite

During the calcination of pure, difficult-to-sinter varieties of limestone and dolomite their preliminary industrial processing, consisting in a calcination firing, and subsequent slaking of the material, allows the production of sintered dolomite and limestone clinker with an apparent density respectively of 3.28–3.31 and 2.96 g/cm 3 at 1400–1500° C.

Calcination - Wikipedia

The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature ...
