Smelting rock ilmenite produces pig iron and titania slag that contains about 75%–80% wt. TiO 2. The production of slags with higher TiO 2 content from rock ilmenite is very difficult, due to the relatively high impurity content of the raw material. Therefore, slag produced from rock ilmenite is mostly sold to TiO 2 pigment producers that use ...

Ilmenite often contains intra-grain chromium (III) oxide known as chromia (Fisher-White et al. 2007), and so untreated low-grade ilmenite ores cannot be used in the sulphate route feedstock. However, either primary ilmenite concentrates (45–55 wt.% TiO 2 ) or granulated slag fines (70–80 wt.% TiO 2 ) are dissolved in 85–92% sulphuric acid ...

The Pulmoddai mineral sand deposit in Sri Lanka is considered as a …

As ilmenite contains only roughly half the amount of TiO 2, its maximum abundance in rutile-free samples might be approximated as twice the amount of rutile required to satisfy Ti* = 1. With a median V concentration of 1310 ppm, ilmenite, when present, is as important a contributor to the whole-rock eclogite V budget as rutile.
