This paper is a contribution to the theory and quantitative understanding of the processes for the production of magnesium, calcium and strontium metals by metallothermic process. In the present study, effect of reductant type was investigated. Thermodynamic simulation of system were made by Fact Sage 6.4 program. In order to produce magnesium metal, effects of reductants “FeSi, Al, Si and CaC2” were investigated. To understand Calcium-oxide reduction system, effects of Al and CaF2 addition were investigated for different temperatures. In the last simulations, SrO reduction parameters were simulated. Al has been selected as main reductant and BaO, CaO, CaC2 were added to mixture as a fluxing and a functional additive. Finally probable phases and minimum reduction temperatures are determined.
