Hematite: A primary ore of iron and a pigment mineral
It is an iron oxide with a stone composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron. Although it was once mined at thousands of locations around the world, today almost all of the production comes from a few dozen large deposits where significant equipment …
Hematite | Physical - Optical Properties, Occurrence, Uses
Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance. The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses.

Iron ore - Wikipedia
Banded iron formations may contain iron in carbonates(sideriteor ankerite) or silicates(minnesotaite, greenalite, or grunerite), but in those mined as iron ores, oxides(magnetiteor hematite) are the principal iron mineral. Banded iron formations are known as taconitewithin North America.
Iron Ore - an overview | ScienceDirect Topics
The stone composition of direct-ship and beneficiated iron ores can be divided into high-grade hematite ores, with 64–67% Fe and low SiO 2 and Al 2 O 3, largely from Brazil and West Africa (e.g., Simandou); a number of Australian and other iron ores with ~ 60–62% Fe; high-LOI martite-goethite Australian ores; and high-LOI Australian CID ...
Hematite - an overview | ScienceDirect Topics
Iron Oxides—Fe 2 O 3 Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

Mar 02, 2016 · Hematite, also spelled as haematite, is the mineral form of iron (III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
Iron
Iron (Fe) is the most abundant element, but it only comprises approximately 6 percent of continental crust. Metallic iron is silvery-white, malleable, ductile, and may be readily magnetized. Elemental iron has a relatively high specific gravity (7.87) and high melting point. Iron is used primarily in the manufacture of iron and steel products.
