From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
BENEFICIATION OF LOW GRADE TITANIUM ORES FROM …
Nithi is between 1.6 to 1.77 percent. The beneficiation of the titanium was done by heating raw biomass-sample in the ratio of 1:10 at temperature range of 500 to 800 oC in closed ceramic crucibles. When heated, iron-rich titanium (ilmenite (2θ = 33.12o)), goethite (2θ =21.51o) and haematite (2θ = 54.11o) were converted to maghemite (2θ = 35.6o
Distinguishing features . Ilmenite is often recognised in many altered igneous rocks (which is most, to some extent) by the production of the white pseudo-mineral leucoxene.Often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimed ilmenite.

A process for treating ilmenite to obtain a beneficiated product having a relatively high titanium dioxide content. Particulate ilmenite is first heated in the presence of a reducing agent to reduce the iron compounds in the ilmenite to ferrous oxide and/or metallic iron. The resulting product is then leached with a dilute inorganic acid to solubilize the reduced iron values.
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
