Abstract

The reduction and melting separation experiment of iron ore containing Al2O3 was performed. The results showed that Al2O3 obviously affected the melting separation behaviors and the carbon content of the iron nugget. When the Al2O3 content in iron ore was 4.59 wt%, the carbon content in the iron nugget was as low as 0.80 wt% and was much lower than the iron ores with lower Al2O3 content, and increased with the increasing of slag basicity. The melting separation and carburiz ation mechanism of high Al2O3 iron ore/coal composite pellet was deduced.
