One of the most important parameters affecting the evolution of the reduction reaction is the coal consumption ratio. Increasing the ratio of mill scale to coal from 1:1 to 1:3 resulted in an increased reduction rate, which decreased the mill scale to coal ratio of 1:3 for a reaction time of 3 h at 900 °C, as discussed in section 3.4.4.
