Ilmenite - Wikipedia
The ilmenite crystal structure consists of an ordered derivative of the corundum structure; in corundum all cations are identical but in ilmenite Fe 2+ and Ti 4+ ions occupy alternating layers perpendicular to the trigonal c axis.
Ilmenite - an overview | ScienceDirect Topics
Ilmenite (FeTiO 3) and rutile (TiO 2) are the most important ores used as raw material for TiO 2. Although natural rutile contains a high amount of TiO 2 with low level of impurities, the mineral is becoming scarce and thus more costly.

An overview of the Namakwa Sands ilmenite smelting operations Slag Slag is tapped into slag pots, 25 tons at a time. After tapping, the slag pots are allowed to air cool for approximately four hours.
Ilmenite - chemeurope.com
Magnesian ilmenite is indicative of kimberlitic paragenesis and forms part of the MARID association of minerals (mica-amphibole-rutile-ilmenite-diopside) assemblage of glimmerite xenoliths. Managaniferous ilmenite is found in granitic rocks and also in carbonatite intrusions where it …
ilmenite operations
Grande Côte Operations The Grande Côte mineral sands operation (GCO) is the largest single dredge mineral sands operation in the world and is managed by an experienced team. Over an expected mine life of at least 25 years, GCO will primarily produce high-quality zircon and ilmenite as well as small amounts of rutile and leucoxene.
An overview of the Namakwa Sands ilmenite smelting operations
ilmenite smelting operations by M. Gous* Synopsis Namakwa Sands is a heavy minerals mining and beneficiation business in the Anglo Base Metals Division, and operates along the West Coast of South Africa. The business encompasses mining, mineral concentration, separation, and smelting operations. The smelting process comprises the carbonaceous reduction of ilmenite to produce titania slag with ...
Ilmenite smelting: the basics T - SAIMM
ilmenite smelting process. Ilmenite has the nominal composition FeO.TiO2. South African beach-sand ilmenites are close to this nominal composition, with the main impurities being MnO, MgO, SiO2 and Al2O3 (amounting to some 3% of the mass of the ilmenite). There are two main routes that are used to upgrade ilmenite, to serve as a feedstock for the production of TiO2 pigment.1 The pigment is ...
Tormin Mineral Sands Operation | Mineral …
Tormin Mineral Sands Operation. Situated on South Africa’s west coast, approximately 400km north of Cape Town, Tormin is a world-class placer beach mineral sands deposit, hosting some of the richest concentrated grades of naturally occurring zircon, ilmenite, rutile, magnetite and garnet. MRC via its South African subsidiary Mineral Sands Resources (Pty) Ltd (MSR) holds a 50% interest in ...
Titanium Ore Processing and Beneficiation
An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. In this case all the gravity circuit including the jigs and tables can be eliminated. This scheme is also applicable on a rutile ore with little or no ilmenite. Generally on complex titanium ores it is advisable to use the ...
Global Locations – Tronox
Ilmenite, natural rutile and zircon are transported to the Smelter by rail from an open-pit mine and concentration plant in Brand-se-Baai. The ilmenite is processed in furnaces to produce saleable titanium dioxide slag and pig iron, while the zircon and natural rutile is stored on site for export. Final products are dispatched globally to either Tronox’s pigment operations or third-party ...
ELECTRO SMELTING OF ILMENITE FOR PRODUCTION OF TiO ...
Ilmenite used for smelting typically contains 36% to 50% TiO2. These lower TiO2 ilmenites are the pre-ferred feedstock for smelting, as the high iron content provides suitable thermodynamic conditions for smelt- ing to take place and high grade pig iron is produced as a valuable by-product. In smelting ilmenite, a temperature in the range of 1650 oC-1700oC is required to ensure that the ...
Ilmenite Activation during Consecutive Redox …
Ilmenite, a natural mineral composed of FeTiO3, is a low-cost and promising oxygen carrier (OC) for solid fuels combustion in a chemical-looping combustion (CLC) system. The aim of this study is to analyze the behavior of ilmenite as an OC in CLC and the changes in its properties through redox cycles. Experiments consisting of reduction−oxidation cycles in a thermogravimetric analyzer were ...
The Top 5 Largest Mining Operations in the …
The Top 5 Largest Mining Operations in the World. Mining is one of the core principals of the decentralized economy. Cryptocurrencies such as Bitcoin rely on mining operations to verify transactions and approve their entry onto the blockchain. Cryptocurrency miners are awarded for completing the proof-of-work algorithm and thereby, adding the next block to the blockchain. This reward can vary ...
Ilmenite - definition of ilmenite by The Free …
il·men·ite (ĭl′mə-nīt′) n. A lustrous black to brownish titanium ore, essentially FeTiO3. [After the Ilmen Mountains, a range of the southern Ural Mountains.] ilmenite (ˈɪlmɪˌnaɪt) n (Minerals) a black mineral found in igneous rocks as layered deposits and in veins. It is the chief source of titanium. Composition: iron titanium oxide ...
Titanium - Rio Tinto - Rio Tinto
Our 70-year-old Rio Tinto Fer et Titane (RTFT) operation in Quebec, Canada, pioneered the process of removing iron and titanium from ilmenite. The RTFT Havre-Saint-Pierre mine in eastern Quebec is home to the largest ilmenite deposit in the world. The ilmenite is then transported to our Sorel-Tracy metallurgic complex, just over an hour from Montreal, for processing into iron and titanium. The ...
Rio Tinto scales back international operation
