Titanium dioxide or titania pigment is prepared commercially from ilmenite, an iron-titanium oxide mineral, by the sulfate process.Ilmenite is digested with H2SO4 to yield a titanium sulfate solution. Subsequently, the solution is hydrolyzed to yield a hydrous titania precipitate that is calcined to produce pigment.

Buddy D. Ratner, Guigen Zhang, in Biomaterials Science (Fourth Edition), 2020 Titanium. In 1791, William Gregor, a Cornish amateur chemist, used a magnet to extract the ore that we now know as ilmenite from a local river. He then extracted the iron from this black powder with hydrochloric acid, and was left with a residue that was the impure oxide of titanium.
the extraction of titanium from ilmenite ores extensive deposits of ilmenite are found in various parts of the world (table i) and considerable attention has been given to upgrading these deposits by removing iron and other minor impurities (chromium, vanadium, etc.) to form synthetic futile (tio2) for pigment use and a source of titanium tetra- …

The heavy mineral sands of Senegal are exploited to extract titanium oxides and zircon. Mining is carried out first by means of a floating dredge and concentration plant which produces a heavy mineral concentrate (HMC) containing on average 78% titanium oxides, 11% zircon and a set of silicate and alumino-silicate minerals. This heavy mineral concentrate is then treated by …
recovery of titanium bearing minerals from the deposit, producing commercial grade ilmenite concentrates (up to 63.7% TiO 2) and rutile grade concentrates (up to 93.4% TiO 2). It was found that, for fine particles, the titanium grade increased greatly when titanium-bearing minerals were separated from the deposit by a Knelson concentrator.
Solutions of ilmenite (FeTiO 3) and a titaniferous slag, in fused Li 2 O. 2B 2 O 3 and Li 2 O. 4B 2 O 3, yield on cooling compounds tentatively identified as LiFe 2. 5 Ti 3 O 9 and Li 2 Fe 3 Ti 2. 5 O 9 respectively. Both compounds are orthorhombic, and have the pseudobrookite structure. The ilmenite solutions yield, in addition, rutile (TiO 2).The yield of rutile increases from about 1 to …
