Description
Hematite is the mineral form of iron oxide, one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on Earth. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. It is mined as the main ore of iron.
Kidney Ore Hematite: Some hematite precipitates in cavities and has the opportunity to form an unrestricted habit. A habit known as ‘kidney ore’ often develops in cavities and is named for its similar visual appearance to an internal organ. This type of chemically precipitated hematite is often relatively uncontaminated with sedimentary clay or host rock inclusions and has a higher purity. The high purity makes this the hematite of choice for making pigments.
