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 titaniarich slag, and molten iron. This is in contrast with the Becher process,

Beneficiation processes Rio Tinto

Roasting process. Ilmenite, as mined, has a high Cr 2 O 3 content which makes is unsuitable for direct smelting to titania slag. Some of this Cr 2 O 3 is removed at the mine when the ilmenite is passed through a magnetic separation step in which the highly susceptible Cr 2 O 3rich fraction of the ilmenite …

Titanium Dioxide (TiO2) Production and Manufacturing Process

TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.
