Kinetic Studies of the Reduction of Ilmenite Ore by Hydrogen
Journal of the Mining and Metallurgical Institute of Japan
The reductions of ilmenite ore by hydrogen were studied over a temperature range of 650•‹ to 800•Ž with thermobalance. The overall reaction is found to consist of two stages and the rate of reduction can be described as follows; where x is fraction of reaction, t is time, k is rate constant and 1-n is reaction order. And then, the reasonable mechanisms of reduction may be presumed as follows; The rate of reduction for reaction (c) was much larger than those of (a) and (b).
