Granular ilmenite is the main mineral used for the recovery of titanium. Granular ilmenite is often associated with titanomagnetite, or distributed in silicate mineral grains, and forms via automorphism and semiautomorphism processes. It has coarse granules and is easily broken and dissociated. Granular ilmenite is about 90% of total ilmenite reserves.
Ilmenite is weakly magnetic mineral sand, grey-black in colour, solid in form and exists in a triangle crystal structure. On the other hand, rutile is reddish-brown and exists in a tetragonal crystal structure. These heavy mineral sands are excavated and dredged, mostly to commercially produce ilmenite, rutile or other titanium oxide ores.

2021-6-2 · Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO3. It is an accessory mineral in igneous rocks, sediments, and sedimentary rocks. Ilmenite has a high resistance to weathering. When rocks containing ilmenite (such as those at Thule) weather, grains of ilmenite disperse with the sediment.
The entire set of observed Bragg reflections is shown in the integrated pattern in Figure 3 and given in Table 4. Interestingly, ilmenite exhibits some azimuthal intensity variations which indicate crystallite texture whereas diffraction of wangdaodeite does not exhibit deviations from random crystallite orientation. (a) Ilmenite; (b) Wangdaodeite.
Symplectic ilmenite is considered to form at a lower pressure and temperature than discrete ilmenite. These intergrowths are protected from a continuous interaction with the magma because of the pyroxene encasement and not because these assemblages are derived from a distinct source or because they were removed from the system.
