  author={Jian Pan and Congcong Yang and Deqing Zhu},
A comparative study on coal-based solid state reduction of preoxidized chromite pellets and chromiteiron ore pellets was conducted to investigate the reduction behavior of these two types of pellets. And the enhancement mechanism of chromite reduction reactions due to the pre-oxidation process of chromite with magnetite was revealed by means of optical microscopy, SEM with EDS. The results show the presence of iron ore and pre-oxidation process both are advantageous to the reduction of chromite… CONTINUE READING
