Haematite is a mineral and one of the most important iron ores, with the chemical formula Fe2O3.
It is a red, gray or black mineral with a metallic luster and is the most common iron oxide mineral found in nature.
The mineral is found in various geological formations, including sedimentary, metamorphic, and igneous rocks.
Haematite is the most important source of iron and is used in the production of steel and other iron-based products.
It is also used in pigments, coatings, and as a polishing compound.
Haematite has a wide range of industrial applications, including in the production of magnetic materials and as a radiation shielding material.
The mineral is widely distributed and is found in many countries, including Australia, Brazil, China, India, Russia, and the United States.
The largest deposits of haematite are found in Australia, Brazil, and Russia.
The quality of haematite varies depending on the geological formation and the impurities present in the mineral. High-grade haematite is preferred for use in steel production due to its high iron content and low impurities.
