Iron ore BHP

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

Magnetite: Mineral information, data and localities.

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Magnetite pigments

Magnetite is a natural iron oxide magnet and primary iron ore. It has a black opaque color with metallic luster and a hardness of 5.5-6 on Mohs Scale. It is the most magnetic out of all the minerals. It was named in 1845 by Wilhelm Karl von Haidinger for the locality at Magnesia, Greece. Black iron oxide has a long history of use as a pigment.
