Hematite has in the past been referred to as natural ore because certain hematite ores contain up to 69% iron and can be directly fed into blast furnaces in the steel milling process. Hematite ore also lends itself to the beneficiation process unlike lower grade magnetite, and is therefore mined as Direct Shipping ore.

The addition of ilmenite ore to hematite ore increased the temperature of melt formation. More titanium (Ti) was distributed in the glass phase with increasing temperature. Morphological change showed that the amount of sinter-bonding phase generated was low, below 1473 K. Weak sinter bonding strength might be caused by the presence of Ti in
