The oxidized pellets, which are prepared form domestic magnetic iron concentrate, show good comprehensive performance and can be used in gas-based shaft furnace to produce direct reduction iron. Lignite and low metamorphic bituminous coal reserves of China for the coal gasification occupies the 50% above of coal reserves about and can meet the needs of the development of the coal chemical industry. Synthesize the demand of coal, the ability of production, the quality of coal gas and the index of energy consumption, select the suitable coal gasification, and finally forms the new gasification-shaft furnace direct reduction iron-making process which takes the coal-formed gas as the reductant and the shaft furnace as the reactor. The new process is an effective way to develop direct reduction iron and low carbon ironmaking in china where nature gas resource is poor and noncoking coal resource is rich.
