Calcined dolomite CALCINOR

Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process.

Study of using dolomite ores as raw materials to produce

The quartz powders were introduced in the calcination process of dolomite to chemically combine with CaO. The effect of calcination temperature and dolomite-to-quartz mass ratio on the properties of calcined raw material as well as the calcination mechanism were studied in order to obtain materials suitable to be used as MgO components in MPC.

Effect of natural dolomite calcination temperature on

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. The surface molar ratio of Ca/Mg decreased from 1.6 to 0.6 by

Calcination chemical process Britannica

Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable.Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.In this process the limestone is brought to a temperature high enough to expel the carbon dioxide

Calcination Wikipedia

OverviewIndustrial processesReactionsAlchemy

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
