On the reduction behavior, structural and mechanical features of iron ore-carbon briquettes

The carbonization process caused significant differences in the optical textures of the carbonized materials, in particular in higher rank coals, where there was a greater range of optical texture sizes compared to the cokes from single coals. The best resistance to compression was observed in the briquettes with the larger optical texture, whereas the best resistance in a drum was that of the briquettes having larger proportion of mosaics. Furthermore, the Fe-coke briquettes produced by cold briquetting and carbonization show self-reducing properties of iron oxides.
