Illmenite

Description

Ilmenite, identified by the chemical formula FeTiO3, is a dense, black mineral primarily composed of iron and titanium oxides. It serves as a significant industrial source for titanium, distinguished from rutile by its iron content; while rutile typically contains less than 15% iron, ilmenite exhibits higher concentrations, frequently reaching up to 40%. The mineral's composition may also include varying levels of manganese, magnesium, and other impurities depending on its geological origin, often appearing alongside materials such as syenite, diorite, or apatite. Geologically, it is extracted from disseminated deposits, vein systems, or massive ore bodies globally, with significant mining operations located in regions including Norway, Australia, Africa, and North America. In industrial applications, raw ilmenite ore is processed through milling and smelting to refine titanium dioxide, utilizing either sulfate or chloride chemical methods. Consequently, the grades available for use in ceramic formulations and glaze chemistry are typically derived from these standardized industrial refining processes.
