The chlorine can be reused in the dehydration process. Thermal reduction. 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.
