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 (CO 3) 2 to MgO and CaCO 3 up to 700 °C and CaCO 3 to CaO from 700 to 900 °C.

Calcination Wikipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide, in order to create cement. The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment. Calcination is carried out in furnaces or reactors (sometimes referred to as kilnsor calciners) of various designs including shaft furna

Magnesium Production by the Pidgeon Process Involving

In analogy to previous studies on the calcination of limestone to lime,12-14the calcination of dolomite can be converted to a thermoneutral process by adding a calculated amount of carbon and oxygen to CaMg(CO3)2. The equilibrium composition as a function of temperature for an initial mixture of CaMg(CO3)2+ 4C + 2.3O2is shown in Figure 3.
