Ilmenite - Wikipedia

Ilmenite ores can also be converted to liquid iron and a titanium rich slag using a smelting process. Ilmenite ore is used as a flux by steelmakers to line blast furnace hearth refractory. Ilmenite sand is also used as a sandblasting agent in the cleaning of diecasting dies.

Ilmenite smelting: the basics T - 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,

Ilmenite for pigment and metal production - oatext.com

For these reasons, titanium slag was used only for making pigment by the sulfuric acid process [7]. The slag was treated in the same way as ilmenite with the exception that no separation of ferrous sulfate was necessary because the bulk of iron was already separated by reduction in the earlier step (Figure 13).
