Ilmenite(Titanium) Mining Process
About Ilmenite & Titanium. Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. It is an oxide mineral of iron and titanium, also known as titanium magnetite, and its composition is FeTiO3. Ilmenite is a heavy (specific gravity 4.7), moderately hard (Mohs hardness 5.6 to 6), opaque black mineral with a submetallic luster.

This material has been classified during many cycles in the pilot plant, so that the probability of agglomeration and blockages is low. Another advantage is that highly cycled ilmenite is known to be more reactive than fresh material (Abad et al., 2011). The average diameter of the particles is d p(av,ilmenite) = 154 μm. Furthermore, an iron ...

ILMENITE SMELTING IN A PILOT SCALE DC FURNACE
Electric arc furnace smelting is one of the main processing routes used to upgrade ilmenite into a suitable titanium feedstock for pigment and sponge producers. During the ilmenite smelting process the iron oxides present in the ilmenite concentrate matrix are reduced to metallic form by using carbon as the reductant. A slag rich in TiO2 and low in FeO content remains, together …
