Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3 .
Even so, titanium is considered to be a rare metal due to its wide-distribution and difficulties in its processing using current technology (Wang et al., 2016). At present, ores containing the minerals of ilmenite (FeTiO 3) and rutile (TiO 2) are the main titanium source of market-value to titanium industry (Kothari, 1974).
Panzhihua ilmenite, located in Sichuan province of southwest China, is the largest ilmenite reserve in the world, with an estimated reserve of 870 million tons.This deposit accounts for more than 90% of the total titanium resource of China and over 35% of the world. In the present processing flowsheet, the ore is first processed with wet low-intensity drum magnetic separator to concentrate ...
The world's largest open cast ilmenite mine is the Tellnes mine located in Sokndal, Norway and run by Titania AS (owned by Kronos Worldwide Inc.), a hard rock ilmenite mine, which produces most of Norway's 380,000t of ilmenite production. In Karhujupukka located in Kolari, northern Finland there is a magnetite-ilmenite ore at around 5 million tons.
Titanium is obtained from various ores that occur naturally on the Earth. Ilmenite (FeTiO3) and rutile (TiO2) are the most important sources of titanium. According to USGS, Ilmenite accounts for about 92% of the world's consumption of titanium minerals. World resources of anatase, ilmenite and rutile total more than 2 billion tonnes.

The ores have a rather uniform titania content, averaging 0.77 percent. Titanium occurs mainly in solid solution in hematite (0.15 to 8 percent) with lesser amounts as ilmenite, anatase, rutile, sphene, leucoxene, and biotite. Magnetite contains 0.1-0.2 percent. High-grade hematite ores generally have all titania in the hematite.

The country hosts a collection of rare earth minerals, including monazite, xenotime and samarskite from tin ore tailings. Egypt; Egypt is rich in monazite, which is collected from ilmenite in the Nile Delta. Brazil; Brazil was one of the first countries to produce rare earth elements and was once well known for it across the world.
Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. 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, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3.. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys.
It is divided into lower, middle, and upper zones, in which the typical minerals are ilmenomagnetite, ilmenite, and apatite, respectively. The middle zone contains a 2-km-long ilmenite ore body that grades between 8 and 48% ilmenite. Ilmenite and magnetite occur mainly as discrete grains in the middle zone and in the upper zone.
Zirconium is also produced as a byproduct of mining the titanium minerals ilmenite and rutile. Niobium and tantalum are commonly found in the minerals pyrochlore and columbite. Cobalt is mined specifically from ores like cobaltite, but also as a byproduct of copper and nickel mining (Raymond, 1995).
Ti-oxide deposit dominated by ilmenite rarely contains more than 300 million tons of ore, with between 10- to 45-percent titanium dioxide (TiO. 2), 32- to 45-percent iron oxide (FeO), and less than 0.2-percent vanadium (V). The origin of these typically discordant ore deposits remains as enigmatic as the magmatic evolution of their host rocks.
