Ilmeniitissä

Ilmeniitissä, also known as ilmenite, is a mineral composed primarily of iron titanium oxide (FeTiO3). It is an important ore mineral for the extraction of titanium, a metal widely used in aerospace, pigment production, and various industrial applications. Ilmenite typically appears as dark gray to black with a metallic or sub-metallic luster and often exhibits a granular or massive habit.

Ilmenite is commonly found in igneous and metamorphic rocks, especially in layered mafic intrusions and volcanic deposits. Major deposits are located in countries such as Australia, South Africa, Canada, India, and Norway. Extraction involves beneficiation processes, including crushing, magnetic separation, and upgrading to produce a high-grade titanium dioxide feedstock.

One of the key properties of ilmenite is its moderate magnetic susceptibility, which aids in mineral separation techniques. When processed, ilmenite yields titanium dioxide (TiO2), essential for manufacturing paints, coatings, plastics, and paper. Titanium's corrosion resistance and strength-to-weight ratio make it valuable in aerospace engineering and military applications.

Ilmenite also contains minor quantities of other elements such as magnesium, iron, and vanadium, which can influence processing and applications. Its stability in geological processes contributes to its abundance and economic importance within the titanium mineral supply chain.

Overall, ilmenite plays a crucial role in the global supply of titanium materials. Its extraction and processing are integral to various industries, emphasizing its significance in both economic and technological contexts.
