Reduction Kinetics of Bayan Obo Associated Iron Niobium Ore

摘要：

　　The mass loss rate of carbon-bearing pellet during reduction process was investigated at the temperature from 900 to 1050 ℃.The results show that temperature is the significant influence factor to the reduction of carbon-beating pellet.In addition,the reduction process includes two stages and the first stage is faster than second stage.Both of steps are controlled by carbon gasification,and that is confirmed by means of the activation energy.
