摘要：

In order to economically extract boron from a boric oxide bearing iron ore by blast furnace process, thermodynamic properties of the MgO-BO1.5-SiO2 system have been investigated. Phase diagram and the activities of the constituent oxides of the MgO-BO1.5-SiO2 ternary system were determined at 1723 K by chemical equilibrium method. Thermodynamic calculations for the equilibrium between MgO-BO1.5-SiO2 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.
