Reduction of magnetite concentrate particles by H2+CO at 1 673 K

Abstract

The purpose of this research was to determine the effect of CO addition to H2 on the reduction kinetics of magnetite concentrate particles at high temperatures. Experiments were carried out at 1 673 K. The replacement of N2 by CO enhanced the reduction rate considerably. The kinetics of CO reduction is slower than that by hydrogen but significant, and the contributions by the two gases are additive.
