The ilmenite, as mined, has a high Cr2O3 content and is not suitable for direct smelting to titania slag. Titanium slag is produced in the mining, refining and smelting of mineral sands to produce titanium dioxide (TiO2) feedstocks used in the production of pigments, titanium metal, welding fluxes and other specialised products.
This invention relates to titanium dioxide pigments and more particularly to the production of titanium dioxide by hydrolysis of a titanium sulfate solution obtained by digesting a titaniferous material with sulfuric acid. The object of the invention is an improved method of producing titanium dioxide pigment in its rutile crystalline form.
Further processing, including smelting of ilmenite to produce titanium dioxide slag then takes place at the central processing complex in Empangeni, 20 km west of Richards Bay. KZN Sands produces ilmenite, slag fines, zircon, rutile, leucoxene, low manganese pig iron and chlorinatable titanium dioxide slag (see section 4).
ILMENITE AND RUTILE India is endowed with large resources of heavy minerals which occur mainly along coastal stretches of the country and also in inland placers. Heavy mineral sands comprise a group of seven minerals, viz, ilmenite, leucoxene (brown ilmenite), rutile, zircon, sillimanite, garnet and monazite. Ilmenite (FeO.TiO 2) and rutile (TiO 2
See also Titanium dioxide pigment . Rutile. Rutile is titanium dioxide which is naturally occurring in Australia, USA, India and South Africa. Synthetic rutile can be produced from naturally occurring ilmenite which is a complex oxide with iron. Rutile is used in the manufacture of titanium dioxide pigment.
process. The principal raw materials for manufacturing titanium dioxide include ilmenite (FeO/TiO2), naturally occurring rutile, or titanium slag. Both anatase and rutile forms of titanium dioxide can be produced by the sulfate process, whereas the chloride process yields the rutile form. Titanium dioxide can be prepared at a high level of purity.

From the commercial perspective, ilmenite is the most important ore of titanium. Most ilmenite is mined for titanium dioxide production. In 2011, about 47% of the titanium dioxide produced worldwide were based on Ilmenite Sand. Finely ground titanium dioxide is a bright white powder widely used as a base pigment in paint, paper and plastics.
Research highlights Various titanium metallurgical processes for the production of titanium dioxide and titanium metal have been reviewed and compared including: Processes to upgrade ilmenite to synthetic rutile. Thermo-chemical Kroll and Hunter processes. Electro-chemical processes for direct reduction of TiO 2 and electro-slag and in-situ electrolysis. Direct hydrometallurgical leach processes.

A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a D.C. arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory ...
