Ilmenite (FeTiO 3) is the essential titanium ore, accounting for up to 47% of the aggregate global production of TiO 2, a whitening pigment.The leading worldwide provider of ilmenite ore is Australia, followed by South Africa, China and Canada. The ore materializes as two alternative morphologies: heavy sand ilmenite, the most utilized morphology, and hard rock.

Producers attributed the increase in prices to higher activity in TiO 2 and rationalisation of the Chinese industry, as well as tighter ilmenite supply owing to lower iron ore prices. Sulphide ilmenite is produced as a byproduct of magnetite, the mining of which takes place in conjunction with iron ore production.
