• In order to economically extract boron from a boric oxide bearing iron ore by blast furnace process, thermodynamic properties of the MgO-BO<SUB>1.5</SUB>-SiO<SUB>2</SUB> system have been investigated. Phase diagram and the activities of the constituent oxides of the MgO-BO<SUB>1.5</SUB>-SiO<SUB>2</SUB> ternary system were determined at 1723 K by chemical equilibrium method. Thermodynamic calculations for the equilibrium between MgO-BO<SUB>1.5</SUB>-SiO<SUB>2</SUB> slag and carbon saturated Fe-B-Si-C alloy were performed and the suitable blast furnace slag composition for the recovery of boron was discussed.
