Ilmenite smelting: the basics

The two main routes to upgrade ilmenite to chlorination feedstock are ilmenite smelting, and the synthetic rutile route. Synthetic rutile is produced by solid-state reactions; for example, in the Becher process (as practised widely in Australia) ilmenite is reduced to a mixture of metallic iron and rutile; the iron is then removed by leaching.
