Ilmenite
Ilmenite is a naturally occurring mineral composed of iron titanium oxide (FeTiO₃). It is the primary source of titanium dioxide (TiO₂), which is widely used in various industries. Ilmenite is recognized for its magnetic properties and is typically found in large quantities in igneous and metamorphic rocks.
Applications:
- Titanium Dioxide Production: Ilmenite is a major raw material used in the production of titanium dioxide, which is a key ingredient in white pigments for paints, coatings, plastics, and paper. Due to its high refractive index and opacity, titanium dioxide derived from ilmenite is highly valued for its ability to provide brightness and durability.
- Metallurgy: In the metallurgical industry, ilmenite is used to produce titanium metal through the Kroll process. Titanium metal is highly sought after in the aerospace, automotive, and medical industries for its lightweight, strength, and corrosion resistance.
- Welding Electrodes: Like rutile, ilmenite is also used in the production of welding electrodes, contributing to the stability and quality of the welding arc.
- Synthetic Rutile Production: Ilmenite can be processed to produce synthetic rutile, which is a purer form of titanium dioxide. This is often done through the Becher process, where ilmenite is reduced and oxidized to remove iron, resulting in a high-purity titanium product.
- Geological Indicator: Ilmenite is used as a geological indicator to locate diamond-bearing kimberlite pipes and is often studied in the context of mineral exploration.
