What Is Ilmenite?

Ilmenite is a naturally occurring titanium-iron oxide mineral with the chemical formula FeTiO3. It is the primary source of titanium dioxide (TiO2), which is used extensively in the manufacture of pigments, coatings, and various other products. Ilmenite is typically found in igneous and metamorphic rocks and is also present in sand deposits.

Physical and Chemical Properties of Ilmenite

• Chemical Formula: FeTiO3
• Color: Black or dark brown
• Luster: Metallic to submetallic
• Hardness: 5-6 on the Mohs scale
• Density: 4.7-4.8 g/cm³
• Crystal System: Trigonal
• Magnetic Properties: Weakly magnetic

Types of Ilmenite Deposits

Ilmenite is found in various geological settings, including:

• Magmatic Deposits: Ilmenite is often associated with large, layered igneous intrusions where it forms as a primary mineral.
• Placer Deposits: Ilmenite is commonly found in beach sands and riverbeds, where it is concentrated by the action of water. These deposits are known as heavy mineral sands.
• Metamorphic Deposits: Ilmenite can also occur in metamorphic rocks that have undergone high-temperature and high-pressure conditions.

Uses of Ilmenite

Ilmenite is primarily used for the extraction of titanium dioxide (TiO2), which has numerous industrial applications:

• Pigments: TiO2 is widely used as a white pigment in paints, coatings, plastics, paper, and cosmetics due to its brightness and opacity.
• Metallurgy: Titanium extracted from ilmenite is used in the production of strong, lightweight, and corrosion-resistant alloys for aerospace, automotive, and medical applications.
• Welding Rods: Ilmenite is used as a coating on welding rods to stabilize the arc and improve the quality of the weld.
• Ceramics: TiO2 is used in the production of ceramics to enhance their properties and improve their durability.
• Environmental Applications: Titanium dioxide is used in photocatalytic coatings that help reduce air pollution and in self-cleaning surfaces.

Benefits of Ilmenite

Ilmenite offers numerous benefits across various industries:

• High TiO2 Content: Ilmenite is a rich source of titanium dioxide, making it highly valuable for pigment production.
• Versatility: The extracted titanium and titanium dioxide have a wide range of applications, from pigments to aerospace components.
• Economic Value: Mining and processing ilmenite contribute significantly to the global economy and provide employment.
• Sustainability: Titanium dioxide can enhance the performance and lifespan of products, contributing to sustainable practices in various industries.

How to Extract Titanium from Ilmenite

The extraction of titanium from ilmenite involves several key processes:

1. Mining: Ilmenite is mined from open-pit or alluvial deposits.
2. Concentration: The ore is concentrated using gravity separation, magnetic separation, or flotation to increase the TiO2 content.
3. Smelting: The concentrated ilmenite is smelted in a furnace to separate the iron and produce titanium slag, which contains a high percentage of TiO2.
4. Purification: The titanium slag is further purified to produce synthetic rutile or titanium dioxide pigment.
5. Chlorination (Optional): In some processes, ilmenite is chlorinated to produce titanium tetrachloride (TiCl4), which is then purified and oxidized to produce high-purity TiO2.
