Abstract: The influence of different temperature and hydrogen flow rate on reduction of Bayan Ebo iron concentrate powder was studied by a visible fluid bed.The results show that increasing hydrogen flow rate helps to improve the reduction efficiency at the same temperature.However,this effect becomes apparent at low temperatures.The influence of temperature has the same tendency as hydrogen flow rate. The kinetics of hydrogen reduction of Bayan Ebo iron concentrate powder was studied by thermo-gravimetric analysis under different temperatures.It indicates that the restrictive factor to is gas phase diffusion. The activation energy first decreases and then increases with the reduction time,and decreasing of the apparent activation energy is more favorable to the acceleration of the reaction. Under the experiment conditions 5~10 mins reaction time can achieve the bigger reduction reaction rate.
