Experiments for obtaining Fe together with V from Jehol titaniferous iron ore, which contains more than 50% Fe, 13 to 14% TiO_2, and 0.3 to 0.56% V_2O_5, have been carried out. The author applied the principle of thermal dressing. and obtained Fe together with V in a metallic state, the TiO_2 with other impurities having been slagged off. The crushed ore was mixed with approximately 10% of carburizing agent and an adequate quantity of flux. The mixture was kept at about 1, 100℃ untill practically all iron was reduced to a metallic form. Then, the temperature was raised to 1, 300℃ in order to effect the thermal dressing. The furnace products were ground and seperated into metallic and slag parts. The metallic recovery was 95% and the Fe content in the metal was 95% and the major portion of V was retained in the reduced metal. In these experiments, the method of thermal dressing has been proved to be an effective method of smelting the titaniferous iron ore.
