Chloride process Wikipedia
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.
