Hematite.
Bauxite consists of goethite, hematite, gibbsite, boehmite, diaspore, kaolinite, and anatase.
Goethite is primarily used as a pigment in paints, coatings, and plastics due to its rich brown color. It is also utilized in the production of iron, as it is an iron oxide mineral found in various ores. Additionally, goethite serves as a valuable component in soil science and environmental studies, particularly in understanding soil composition and mineralogy. Its applications extend to ceramics and as a filler in construction materials.
The chemical formula of goethite is FeO(OH).
