Calcium Metal - an overview | ScienceDirect Topics

The production process of calcium metal by the metallothermic reduction process (see Equation 2.9.43) is shown in Figure 2.9.43. The raw material CaCO 3 is calcined to produce CaO. Low magnesia content (MgO) is preferred for the reduction feed materials because magnesia is preferentially reduced in this process, thus lowering the reaction efficiency for calcium metal.
