Rutile (titanium dioxide) and ilmenite (35% - 65% titanium dioxide) are the two primary sources of titanium products, with ilmenite the most abundant (Force, E.R, 1991). Ilmenite ore is sourced through the mining of magmatic and heavy mineral sand (also referred to as placer) deposits.

tury, mining of ilmenite ore bodies in the Egersund area, and also farther southeast in the Sokndal area, commenced as iron ore mining, with Blåfjell as the most important deposit. Before the turn of the century the very large ilmenite ore reserves within the Storgangen ilmenite norite body were known (e.g. Vogt 1887, 1892, Kolderup 1896).
In this research, the microwave energy was used to modify the physicochemical properties of ilmenite surface for improvement of ilmenite floatability. The XPS analysis showed that microwave irradiation oxidizes the Fe2+ ions to Fe3+ ones; and the relative content of Fe3+ on the surface of ilmenite increases from 48.5% to 66%.
Magnetite resembles a number of other metal ores, but it is the only common mineral that exhibits magnetism. So magnetism alone is sufficient to distinguish relatively pure magnetite samples.

World consumption rises approximately 5% to 8% per annum, with demand growth most strongly centred in Asian economies. World demand in 2004 was 335,000 tonnes of TiO 2 units, representing about 2.4 million tonnes of ilmenite. Ilmenite is converted into titanium dioxide via the sulfate process.
High-grade ore contains 30–40% magnetite and 28–30% ilmenite. Chlorite, hornblende, some plagioclase, and pyrite (up to 1–2%) make up the gangue. Two main components for TiO 2-pigment production, ilmenite ore from Otanmäki and sulfuric acid, were the domestic raw materials for the then active titanium pigment factory founded in Pori in …

An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. In this case all the gravity circuit including the jigs and tables can be eliminated. This scheme is also applicable on a rutile ore with little or no ilmenite.
The addition of a small amount of iron powder (0.1 kg iron powder for 1 kg ilmenite ore) was proved to largely enhanced the leaching rates of both iron and titanium. When the solid/liquid ratio was increased from 1/20 to 1/8, complete dissolution of both iron and titanium was achieved in 1.5 h with iron powder addition compared with 2.5 h under …
