Ilmenite smelting: the basics - SAIMM

In ilmenite smelting, the iron content of the oxide is also lowered by reduction to metallic iron, but this takes place in the liquid state, at a much higher temperature (of around 1650°C). Ilmenite smelting thus yields two products: a titania-rich slag, and molten iron. This is in contrast with the Becher process, where the iron is removed as ...
