Ilmenite

Ilmenite is a naturally occurring mineral comprised primarily of iron titanium dioxide, as well as other elements such as magnesium and manganese. It is highly magnetic and can be isolated from other minerals by magnetic separators and other processes. Ilmenite can be further separated from iron through a smelting process to make chloride-process titanium slag or sulfate-process titanium slag. It can also be converted into synthetic rutile. All are used as feedstock for the production of titanium dioxide pigment and titanium metals.
