  • 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,

  • Titania-Slag - Production Process , Technology ...

    The smelting process comprises the carbonaceous reduction of ilmenite to produce titania slag with a TiO2 content of 86%, and iron with a carbon content of 2.5%. In the Ti slag production process, the iron oxides are reduced to metallic iron, thereby producing a TiO2-rich slag and high purity iron.
