Hematite - Natural minerals and crystals
Hematite is an iron oxide, it is one of the most abundant minerals on Earth and a major component of sedimentary and metamorphic raw rocks and minerals">rocks. Its name derives from the Greek "haimatites", meaning "of blood", in reference to its characteristic red color when it is in fine powder. hematite can arise from the precipitation of iron oxide in water, from the weathering of other iron minerals, or from metamorphic processes. hematite deposits are often associated with other iron minerals, such as magnetite, and with iron-rich sedimentary raw rocks and minerals">rocks, such as oolitic iron ores. hematite is a relatively hard and dense mineral. Its color and luster vary depending on its purity and the presence of other minerals. hematite has many industrial applications. It is mainly used as an iron ore for the production of steel. In addition, hematite is used as a natural pigment in paints and ceramics, as well as an abrasive. Due to its characteristic red color when powdered, hematite was also used as a natural dye in ancient times.
