Chemistry of Titanium
Titanium Extraction Titanium cannot be extracted by reducing the ore using carbon as a cheap reducing agent, like with iron. The problem is that titanium forms a carbide, TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle.

Extraction of Titanium and Iron from Ilmenite with Fluosilicic …
The effects of leach temperature, acid concentration, and particle size were investigated for the rate at which Ti and Fe are extracted from the ilmenite. Within the leach time studied, the extraction data fit a shrinking-core model with the rate-controlling step being H2SiF6 through an ash layer resulting from a heterogeneous leaching reaction.

A third mineral, leucoxene, is an alteration of ilmenite from which a portion of the iron has been naturally leached. It has no specific titanium content. Titanium minerals occur in alluvial and volcanic formations. Deposits usually contain between 3 and 12 percent heavy minerals, consisting of ilmenite, rutile, leucoxene, zircon, and monazite.
