Two TiO2 feeds were used, i.e. ilmenite and CG slag fines. The analyses of these materials are given in Table I and II. The particle size of the ilmenite ranged between 46 and 212 μm with an average of 117 m. Ninety per cent of the chloride grades slag fines are smaller than 70 μm and the d50 is about 30 m. Duff coal was used as reducing agent.

Ilmenite-smelting furnaces, in particular, must be operated with a "freeze lining" to prevent attack of the sidewall refractory material by the corrosive liquid high-titiania slag. 1 Because the freeze lining consists of slag solidified from the slag bath, it interacts both chemically and thermally with the slag bath.

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

The chloride process is used to separate titanium from its ores. In this process, the feedstock is treated at 1000 °C with carbon and chlorine gas, giving titanium tetrachloride.Typical is the conversion starting from the ore ilmenite:. 2 FeTiO 3 + 7 Cl 2 + 6 C → 2 TiCl 4 + 2 FeCl 3 + 6 CO. The process is a variant of a carbothermic reaction, which exploits the reducing power of carbon.
