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.

Dolomite theoretically contains CaCO3 54.35 % and MgCO3 45.65 % or CaO 30.4 %, MgO 21.9 % and CO2 47.7 %. However, in nature, dolomite is not available in this exact proportion. Hence generally the rock containing 40-45 % MgCO3 is usually called dolomite. When MgCO3 is less than 40 % but more than 20 % then the limestone is called dolomitic ...

Magnesium Production by the Pidgeon Process Involving ...
(a) Conversion of dolomite by calcination to “dolime”, a mixture of MgO and CaO. This step, carried out at 1573 K, is highly endothermic, and releases CO2 both from the reaction itself and from the fuel combusted for process heat: (b) The production of the alloy ferrosilicon for the reduction of dolime.

magnesium processing | Techniques & Methods | Britannica
In thermal production, dolomite is calcined to magnesium oxide (MgO) and lime (CaO), and these are reduced by silicon (Si), yielding magnesium gas and a slag of dicalcium silicate. The basic reaction, is endothermic—that is, heat must be applied to initiate and sustain it.
Dolomite - an overview | ScienceDirect Topics
The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, & Ohtsuka, 2010). The stone composition of dolomite varies from source to source, but it generally contains 30 wt.% CaO, 21 wt.% MgO, and 45 wt.% CO 2. Dolomite also contains the trace minerals SiO 2, Fe 2 O 3, and Al 2 O 3.
Magnesium oxide: A Forgotten Specialty Chemical
Despite being a simple operation, the high energy costs involved in the production of MgO from saline water sources, results in the final product being more expensive than MgO from mineral origin. In the production of MgO from marine sources (less concentrated), the magnesium salt is precipitated as hydroxide, purified using dolomite
