Ilmenite - Wikipedia

Ilmenite, also known as manaccanite, 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, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Neodymium - Wikipedia

Neodymium is a chemical element with the symbol Nd and atomic number 60. Neodymium belongs to the lanthanide series and is a rare-earth element.It is a hard, slightly malleable silvery metal that quickly tarnishes in air and moisture.
