Abstract

Synthetic fayalite slags have been reduced in laboratory experiments at temperatures from 12501450 °C, using either a floating graphite disk or immersed graphite rod. The rate of reduction increased with increasing temperature and increasing magnetite contents. The CO/CO 2 ratio of the gases formed during the reduction process was found to be nearly in thermodynamic equilibrium with the liquid slag. For fayalite, the reduction rate which is given by Rate ( mol O m 2 ⋅ s ) = 5.39 ⋅ 10 6 ⋅ exp ( − 2 9 , 6 0 0 T ( K ) )
